I'm creating a pivot table using jqgrid with group headers. I do some calculation on input data to figure out if combined column width would exceed the fixed width of grid. If it does not exceed then i would change shrinkToFit : truefor grid to occupy full width. If I do it, then dragging column width creates alignment issues between header and body.
Problem gets worse if frozen column are enabled. The fixed header div wont expand like the column underneath it if shrinkToFit is enabled.
Here is a demo to understand the problem : http://codepen.io/anon/pen/NbxWrQ
Any leads will be helpful.
Thanks in advance.
You can use a GeneXus HTML table to layout text blocks and attributes. If I add a second table to contain some other information that I want to conditionally display, quite often, the first cell is a different width to the first cells of the table stacked above it.
How do you make all the columns/cells the same width so that stacked tables display with their contents correctly aligned?
This is for GeneXus Web in Evo 2 & 3.
Thanks
Put a value in the width property of the client table first cell.
So, put the same value in the width property of the password table first cell.
Remember that the width value must be enough for both tables. In your case, the biggest textblock is the "Client Name". So, choose a width enough for that.
Best regards.
If you don't set a width, HTML will assume the minimum width required to accommodate the content. If you don't want it to be set automatically when when the page is displayed, you have to decide on a width.
In your case, you have to put the same width value for a cell (any cell) in the first column of both tables.
Is it possible to set slickgrid row height depending upon the content size.
If any possibilities to wrap text in a particular cell and the corresponding row to the slickgrid.
Thanks,

I want slickgrid to autosize the columns based on the widest content or header text - whichever is wider. In simpler terms, I want it to simulate the default behavior of regular HTML tables when it comes to column sizing. How can I do it in slickgrid?
When constructing your options, you can use forceFitColumns: true
var options = {
enableCellNavigation: true,
forceFitColumns: true
};
This will make the columns fill the entire width of your grid div.
The OP is looking for columns to grow to match their content. grid.autosizeColumns() grows the cells to fit the parent container, which is not the same thing.
I have added this feature, and it is about as manual as you might imagine. You loop through the displayed cells and measure each one, saving the widest cell and using that width to set the width of your column. SlickGrid gives you good access to the cells in the viewport, so that works nicely.
The measurement algorithm is your big decision. You may put the content off screen and measure it, as #jay suggests. This works, but it is the slowest method, as it requires a repaint to insert, and a repaint when you remove. There may be ways to optimize. The solution I went with is to measure the width of every letter in the alphabet, as well as other typographic characters we come across, and sum them to generate a width. Yes, this sounds absurd. It has many constraints: The font size must be the same, it doesn't support images, there can't be any line returns, and more. If you can live with the constraints though, you can calculate sizes for a huge grid viewport in <5ms, because the character widths are only measured once.
After you get the sizes of the columns, you assign them to your columns using grid.setColumns().
Slickgrid will not support column auto size based on data.You need to write a plugin or fork the slickgrid core to modify.
Here is the link I have created a plugin to handle slickgrid auto size
https://github.com/naresh-n/slickgrid-column-data-autosize
I added this after the grid is drawn and it works fine.
$(window).resize(function() {
var cols = grid.getColumns();
grid.setColumns(cols);
})
You should be able to call the autosizeColumns() method of the grid object.
grid.autosizeColumns();
Make this simple adjustment to Naresh's https://github.com/naresh-n/slickgrid-column-data-autosize, on the init function:
Add $container.ready(resizeAllColumns); to the init function.
This ensures the columns autoresize on initial load
Insert the text into an off-screen element and retrieve the width of the element. This is what excanvas does to measure text. Use this to set the width of the column since it's expecting a pixel value.
How do you force a row to be a given height? I have a grid that has a column that sometimes has lengthy data and the rows auto-size to fit it in. I'd like to force the rows to remain a uniform height, however all of my searches seem yield results from people trying to achieve the exact opposite.
What you need to do is just set the CSS attribute 'height' of the row (of the <tr>) element. It is important that you can do this only after the row will be created. So you have to place the changing of the 'height' inside of loadComplete of gridComplete event handle.
The answer contain working demos. The usage of setRowData inside of the loop is not the best way from the performance side, but nevertheless the demos shows the main idea how to set the fixed row height dynamically.
