I set forceFitColumns: false to user can to set any columns width
gridOptions: {
forceFitColumns: false,
enableAutoSizeColumns: false
}
1.Set any columns width enter image description here
but if user would like to set ForceFitColumns, then grid fit to window.
Next if i refresh grid, I can't see option to set forceFitColumns to true.
I would like grid to remember that ForceFitColums option (maybe in Preset?)
Click Force fit columns enter image description here
Refresh grid enter image description here

I've got a Xamarin Forms cross-platform application (iOS and Android), and on one of the screens I want a list with details:
Heading 1
Detail 1
Detail 2
Detail 3
Heading 2
Detail 1
Heading 3
Detail 1
Detail 2
As you can see, the amount of detail under each heading is variable.
I want the page to display at first with just the headings:
Heading 1
Heading 2
Heading 3
And then when the user presses on a heading, the details for that particular heading appear. Pretty standard stuff.
I've tried several different ways to get this to work, the only path that seems open to me is to have a StackLayout where I define a bunch of labels:
new StackLayout
{
Orientation = StackOrientation.Vertical,
Children =
{
new Label { Text = "Heading 1" },
new Label { Text = " Detail 1\n Detail 2\n Detail 3", IsVisible = false },
new Label { Text = "Heading 2" },
new Label { Text = " Detail 1", IsVisible = false },
new Label { Text = "Heading 3" },
new Label { Text = " Detail 1\n Detail 2", IsVisible = false }
}
}
I then add a TapGestureRecognizer to the heading labels, and when tapped I toggle the value of IsVisible for the detail labels. It works!
The only thing I don't like, is that there is no transition. I click on the heading label and BAM the detail label appears (correctly pushing down all the following labels to make space for itself). I would like an animation so that when I click on the header, the space beneath the header "slowly" opens up to reveal the detail.
As I read about animations online, one possibility is to set the HeightRequest of the detail labels to zero (instead of hiding them with IsVisible=false) and then creating an animation that "slowly" changes the HeightRequest from zero to the actual height of the label. And that's where I run into a problem.
I can't figure out how to get Xamarin to tell me the height of my "details" label.
If I inspect the Height and HeightRequest properties of my details label right after creating it, they are both -1 (no big surprise there). If I inspect those same two properties when I click on the heading, they are still -1. The only way I've found to get the height of my detail label, is to set the detail label visible, call ForceLayout() on my stack layout, store the detail label height, and then set the detail label invisible again. The problem with that is that I sometimes see the detail label flash visible for an instant while I do this.
What's the best/recommended way to accomplish my desired UI?
You can use the Animation API.
Read the blog about it - Creating Animations with Xamarin.Forms.
In particular for your scenario you can use the FadeTo method to animate the Opacity property of a Visual Element.
Eg :
await image.FadeTo (1, 4000);
For more information, see Animation.
In your case my suggested approach would be for showing a label, to set opacity of label to 0, then make it visible, and then use FadeTo to make the opacity to 1.
Use the opposite to hide the label, set opacity 0 via FadeTo, then set IsVisible to false.
If I understand right your problem the only thing you need is to avoid the flash on the label, if this is the case then you can set the Opacity to 0, in this way the label will not be visible until you set again the opacity to 1.
I can suggest you to make a custom XF control (to use as item DataTemplate) as follow:
2 vertical parts:
The header part (A) (when you click on it it will show the second part)
The second part is a 'Listview' control (B) that is empty at the beginning
When you click on (A):
it will show (B)
It will start to populate (B) with your details elements
The trick in my mind is to implement a method that populate the listview (B) item by item (getting them from your viewmodel) with some delay (a few milliseconds) between each insertion and maybe a 'fadeTo' effect too in the same time.
You can see here what I mean (see the "Fade" section):
Insert / fade list item effect sample in HTML
You can improve your template as you want, by embedding the two parts into a 'border' for instance, to make a graphical separation...
Tell me if it's unclear, all you need is time :)
And maybe if you are ready, you can try to make native controls / animations...
Regarding free-jqgrid 4.9.2, does it automatically handle column width? No, then what's the proper way to handle this?
1) VIN & Year columns contain too much free spaces
2) Trim contains few records that are too long to fit into column's width (Such as 1993 Mitsubishi 3000GT 2 Dr VR-4 Turbo AWD Hatchback)
Also, does jqGrid have true/false "word wrap" setting somewhere?
Demo is found at link removed
Auto-width adjustment exist in free jqGrid starting with 4.8 version. Free jqGrid still not handle the width of all columns automatically. One need add some additional properties in colModel for the columns which width should be set based on the width on the most long content and to set some additional options.
Your current code uses width: 190 for the column 'Vin' and don't specifies any width property for any other columns, so default value width: 150 will be used. Additionally you use width: 1022 option of jqGrid and wrong option autoWidth: true (instead of autowidth: true) which will be ignored. It means that the width of the div (bDiv or body div) over the grid will be set to 1022px and the user can use horizontal scrollbar to see all columns.
I would recommend you to read the wiki article. You can add autoResizable: true property to some specific columns or to use cmTemplate: { autoResizable: true } to add the property in all columns. As the result the content of every cell of the grid will be wrapped in <span class="ui-jqgrid-cell-wrapper">...</span>. It allows free jqGrid to get the exact width of content for all cells of the column and then calculate the max from the values. So the user can double-click on the column resizer (between the columns) to set the width to the best value. During the width calculation jqGrid the width of the column header with the width of sorting icon additionally to the width of the grid cells of the column. One can use autoResizing: { compact: true } option to reduce the width of the columns which don't have visible sorting icon. The last common option is autoresizeOnLoad: true which I would recommend you to use. It will set the width of the columns having autoResizable: true property to the best value.
So I would recommend you to add the following option to your grid:
cmTemplate: { autoResizable: true },
autoResizing: { compact: true },
autoresizeOnLoad: true
After that the width of column will looks much better.
If you prefer to wrap the text of some columns if it is too long then you can use CSS settings described in the old answer and set maxColWidth property of autoResizing of the column (in colModel) or global setting maxColWidth of autoResizing option of the grid to the max width of the column. More long text will be wrapped.
I have created a table then put a Textbox named "txtTextBox" into a cell of table. The width of the Textbox is 2 inch. In code I change width of Textbox like below
There are 2 case when report viewed:
Case 1: new width > designed width (2inch)
txtTest.Width = Unit.Inch(2.5); ==> The Textbox is showed longer. It is right
Case 2: new width < designed width (2inch)
txtTest.Width = Unit.Inch(1.5); ==> The Textbox is still showed with 2 inch. Expected it should shorter
how to resize column table fit with new width of Textbox?
Telerik doesn't allow width changes after items initialized. You must define your items programmatically instead of designer to do this.

When the datatype is Date, the kendo grid uses a kendo datepicker with dropdown calendar for the column.
The datepicker's dropdown calendar usually aligns itself flush with the left edge of the input box. If there isn't room for that, it is moved to the left, but not quite enough. This presents a problem when the rightmost column in the grid is a Date, and the grid is occupying 100% of the width available on the screen: the Saturday column in the dropdown calendar gets "cut off". See pic attached.
Is it possible to tell the calendar dropdown (for a particular column) to align itself flush with the right edge of the text input?
I know that bug. Your datepicker animation container is hidden under right scrollbar. If you set body overflow to hidden, you will not have a scrollbars and calendar will fit and touch right border of screen, like in this example: http://dojo.telerik.com/UCOhA
However if you can't turn off the body scrollbars you need to set calendar position manually dirty way like this:
$("#piker").kendoDatePicker({
open: function(e) {
//setTimeout to let kendo make k-animation-container element at first open
setTimeout(function(){
var animationContainer = $("#" + e.sender.element.attr("id") + "_dateview").parent();
var left = e.sender.element.offset().left + e.sender.element.closest('.k-datepicker').width() - animationContainer.width();
animationContainer.css('left', left);
});
},
//turnoff the animation to avoid strange visual effects
animation: {
open: {
duration: 0
}
}
});
Running example: http://dojo.telerik.com/Imiqa/2
I'm using SlickGrid and struggling to find an elegant solution to the following:
All columns must have a specific initial width when first rendered but be resizable afterwards
The final column should auto fill the remaining column space when the window is resized
I've seen:
Make one column fill remaining space in SlickGrid without messing up explicit width columns
resizing of grid when resizing browser window
How do I autosize the column in SlickGrid?
But these don't seem to quite do what I need.
If I use the forceFitColumns option, then all columns will autosize (unless I put a maxsize on them).
Using resizeCanvas on window.resize works well - but it still only works if forceFitColumns is true.
If I set minWidth=maxWidth - then I can't resize the column.
Any suggestions?
I'm not sure it would correct all your problem but in my case I do use the forceFitColumns and then depending how I want my column to react in size I will use a combination of minWidth and width, and in some cases the ones that will never exceed a certain width, I would then use a maxWidth as well. Now the problem you have is when setting the minWidth to be the same with as maxWidth this of course will make it unresizable, well think about it you set a minimum and a maximum, SlickGrid is respecting it by now being able to size it afterwards. I also have my grid which takes 95% width of my screen so I have a little padding on the side and with it I use a auto-resize using jQuery.
Here is my code:
// HTML Grid Container
<div id="myGridContainer" style="width:95%;">
<div class="grid-header" style="width:100%">
<label>ECO: Log / Slickgrid</label>
<span style="float:right" class="ui-icon ui-icon-search" title="Toggle search panel" onclick="toggleFilterRow1()"></span>
</div>
<div id="myGrid" style="width:100%;height:600px;"></div>
<div id="myPager"></div>
</div>
// My SlickGrid Options
var options = {
enableCellNavigation: true,
forceFitColumns: true
};
// The browser auto-resize
$(window).resize(function () {
$("#myGrid").width($("myGridContainer").width());
$(".slick-viewport").width($("#myGrid").width());
grid.resizeCanvas();
});
EDIT
I also was annoyed by the fact that using all of these together is blocking you from resizing the width of the column. I came up with a different solution, much later after, which makes the fields to expand (take available width) and does not block you afterwards on resizing the width. So this new solution I believe is giving you exactly what you are looking for... First of all remove the maxWidth property and only use minWidth and width, actually you could probably use only the width if you wanted. Now I had to unfortunately, modify 1 of the core file slick.grid.js with the following code:
//-- slick.grid.js --//
// on line 69 insert this code
autoExpandColumns: false,
// on line 1614 PREVIOUS CODE
if (options.forceFitColumns) {
autosizeColumns();
}
// on line 1614 change to this NEW CODE
if (options.forceFitColumns || options.autoExpandColumns) {
autosizeColumns();
}
then going back to my grid definition, I replace my previous options with this:
// My NEW SlickGrid Options
var options = {
enableCellNavigation: true,
forceFitColumns: false, // make sure the force fit is false
autoExpandColumns: true // <-- our new property is now usable
};
with this new change it has some functionality of the force fit (expanding) but does not restrict you on resizing your columns width afterwards like the force fit does. I also tested it with the columnPicker, if you hide a column it's resizing the others accordingly. I also modified the file slick.columnpicker.js to include a checkbox for that property but that is totally optional...I can add the code for that too if any of you want it as well. Voila!!! :)
EDIT #2
I realized much later that there's no need to modify the core file, we can simply call grid.autosizeColumns() after the grid creation. Like this
var options = { forceFitColumns: false };
grid = new Slick.Grid("#myGrid", data, columns, options);
// will take available space only on first load
grid.autosizeColumns();
This will automatically resize the columns to fit the screen on first load but will not give you the restriction of the forceFitcolumns flag.
I know it's kind late for this reply.
But i've managed to do that without having to change things at slick.grid.js or set min/maxWidth at columns array.
Instead what i did was to iterate through the columns array adding the values of "width" field of each column and then i've did a simple math count to set the last column width as innerWidth - totalColumsWidth + lastColumnWidth.
Code:
function lastColumnWidth(columns)
{
var widthSum = 0;
angular.forEach(columns, function(col) {
if(col.width) { widthSum = col.width + widthSum; }
});
if(window.innerWidth > widthSum) {
columns[columns.length-1].width = columns[columns.length-1].width + (window.innerWidth - widthSum);
}
return columns;
}
