What is the best way to set a saved grid state after the angular-slickgrid has already been created? The Grid State/Presets - Wiki explains setting the saved state on load by setting the gridOptions.presets. In my case, I would like to update the grid state when the underlying saved state has changed in local storage (perhaps saved from another instantiation of the app), and apply the state to the current slickgrid. If I update the gridOptions.presets, is there a method I can call to force the grid to update with the new presets?
Please note that I'm the author of Angular-Slickgrid.
The answer is No it's called Presets for a reason, it only works when creating the grid...but you can still do it with a few method calls. So if you really wanted to use the Grid State then you'll have to save it yourself and then reload the entire grid after applying all previous State. The Grid State that can be applied dynamically are the Filters and Sorting which you can see in Example 4 and Example 25 (with a button click or a dropdown selection like the last example). I did later add a method to change the columns as well and that one is demoed under this Slickgrid-Universal Example 11, in fact that demo will show you exactly the way you want to do it, you can follow the code here.
for a short code sample, you'll need to get the angularGrid instance from (onAngularGridCreated) and then use it to dynamically change the grid. It shows you all the options, you can skip any of them if you don't need or want to change that option.
angularGridReady(angularGrid: AngularGridInstance) {
this.angularGrid = angularGrid;
}
// the `selectedView` should be the result of your Grid State
changeGridView(selectedView: GridState) {
if (selectedView) {
const columns = selectedView?.columns ?? [];
const filters = selectedView?.filters ?? [];
const sorters = selectedView?.sorters ?? [];
this.angularGrid.filterService.updateFilters(filters as CurrentFilter[]);
this.angularGrid.sortService.updateSorting(sorters as CurrentSorter[]);
this.angularGrid.gridStateService.changeColumnsArrangement(columns);
// if you have a frozen grid (pinning)
this.angularGrid.gridService.setPinning(pinning);
} else {
// to reset the grid
this.angularGrid.filterService.clearFilters();
this.angularGrid.sortService.clearSorting(); this.angularGrid.gridStateService.changeColumnsArrangement([...this.columnDefinitions].map(col => ({ columnId: `${col.id}` })));
// if you have a frozen grid (pinning)
this.angularGrid.gridService.clearPinning();
}
// you might want to scroll back to top of the grid if filters are changed
this.angularGrid.slickGrid.scrollColumnIntoView(0);
}
You might not need to re-render the grid but in case the grid UI doesn't show correctly, you could force a re-render of the grid by invalidating all its rows
this.angularGrid.slickGrid.invalidate();

I'm very new to writing script for Google Sheets, and I'm attempting to create a spreadsheet that will only display a dropdown in a column ("Provisional Notes") if the value in a column ("Certified or Provisional" is "Provisional." If it is "Certified," the user is be able to enter data freely. I'm also wanting to remove the validation if the value changes from "Provisional". I also need the solution to run on the Google Sheets App, as this spreadsheet will be run on an iPad and/or a smartphone.
I've done quite a bit of searching, and only seem to find dropdowns that depend on other dropdowns, rather than leaving a cell blank if the initial dropdown is a certain value.
What I have come up with so far only runs once (even though I've attempted to have it occur on every edit?) Also, if the value changes from Provisional to Certified, the validation does not get removed.
For my practice, I've applied it to only 2 specific cells, rather than the entire 2 columns.
function onEdit2(e){
var dropdownCell = SpreadsheetApp.getActive().getRange('P2');
var certCell = SpreadsheetApp.getActive().getRange('J2');
var rule = SpreadsheetApp.newDataValidation().requireValueInList(['Test 1', 'Test 2'], true).build();
function insertDropdown(){
if(e.certCell.getValue() === "P"){
dropdownCell.setDataValidation(rule);
}
}
}
I greatly appreciate all suggestions!
To delete a data validation you just need to use the method setDataValidation() and set its value to null to delete the data validation present on that cell.
In the following code example, depending on the value inserted I am adding or deleting the data validation. This code example has self explanatory comments:
function onEdit(e) {
// get sheet
var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet1');
// if modifications happen in A
if(e.range.getColumn()==1){
// check inserted value
if(e.range.getValue()=='Provisional'){
// create rule from a list range and set it to the same row in column B
var rule = SpreadsheetApp.newDataValidation().requireValueInList(['A','B']).setAllowInvalid(false).build();
sheet.getRange(e.range.getRow(),2).setDataValidation(rule);
}
// if it is set to certified
if(e.range.getValue()=='Certified'){
// delete any data validation that may have been in its adjacent cell
sheet.getRange(e.range.getRow(),2).setDataValidation(null);
}
}
}
I am trying to change the recordtext of a display grid to a custom format. I am using a treeview as the selector that refreshes the display grid. I need to find the total records for the grid and I am able to get this value using the getGridParam records method when I click on the treeview node and load the display grid.
However, after I get this value and try to create the custom recordtext, the record count is the previous value, not the current records count. I know that the gridComplete happens before the loadComplete, but even placing the get in the gridComplete and the set int he loadComplete, it still doesn't work, even with a reloadGrid trigger. If I click on the treeview node twice, I get the correct value.
I am thinking it is a timing issue as to when the new value is ready to set the recordtext. Any help would be great, thanks in advance.
I recommend you to try updatepager method, which updates the information on the pager. Alternatively you can do for example the following:
loadComplete: function () {
var p = $(this).jqGrid("getGridParam");
p.records = 123;
p.recordtext = "My View {0} - {1} of <i>{2}<i>";
this.updatepager();
}
to see the viewrecords
So what I'm trying to accomplish is when the grid is fully loaded, I loop over a certain column that contains checkboxes. Depending on the value of the checkbox I should be able to disable it.
Problem is that I can't access the html element that's there. Am i doing something wrong or overlooking something?
What i've tried:
loadComplete: function() {
// Fetch all the ID's of the rows
var rows = $("#table").getDataIDs();
// Loop over the rows
if(rows.length != 0){
for(i=0; i < rows.length; i++) {
// Get the data so we test on a certain condition
var row = $("#table").jqGrid("getRowData", rows[i]);
if (row.gridCheckbox == 1) {
//disable the element
row.prop("disabled", "disabled");
}
}
}
}
It's important to understand that changing one element on the page follow in the most cases to web browser reflow: validation whether some property (position for example) need be changed in all other elements on the page. If you do changes in the loop then your JavaScript code can be really slow.
Thus it's strictly recommended to reduce the number of changes of the DOM. Especially to reduce the number of changes jqGrid provides rowattr, cellattr and custom formatters. If you need for example to set disabled attribute on some rows then you should now do this in loadComplete, but to use rowattr instead to inform jqGrid that some additional attributes (disabled="disabled") should be set on some rows. jqGrid collect first the string representation of the whole table body and it use one assignment of innerHTML to fill the whole body of the grid in one DOM operation. It improves essentially the performance. See code example in the old answer.
Is there any way i can hide HOT columns from javascript?
The requirement is such that the column to hide will come as a parameter in javascript and based on that the respective column will show hide accordingly.
The HOT has rowHeaders and colHeaders and the data with 20 columns.
Please advise.
OUTDATED SOLUTION
Ok I founnd a possible solution. I tested it out on my own system but it's actually quite simple.
You should be using a customRenderer in your columns option. Read up about this if you aren't already. The idea is that you're giving each cell its own renderer. In this custom function, you can do something like this:
var colsToHide = [3,4,6]; // hide the fourth, fifth, and seventh columns
function getCustomRenderer() {
return function(instance, td, row, col, prop, value, cellProperties) {
if (colsToHide.indexOf(col) > -1) {
td.hidden = true;
} else {
td.hidden = false;
}
}
}
What this renderer does is hide the cells that the var colsToHide specify. All you do now is add a DOM element that lets the user pick which and so every time the table gets rendered (which happens basically after any change, or manually triggered need be), the cells in the columns specified will be hidden, keeping the data array intact like you described. And when not in colsToHide they are re-rendered so make sure you get that working as well.
Here I implemented it with very basic functionality. Just enter the index of a column into the input fields and watch the magic happen.

Better Solution: handsontable: hide some columns without changing data array/object
There is a simple form that has 6 dropdownlists and a gridview. When any of the dropdownlists change the value filters the grid by altering the selectcommand. A user can navigate in another page through a row of the grid.
From the other page a user has a back button that loads the page WITH a querystring which has the values of the dropdownlists.
I want to accomplish 2 things:
1) To put the values in the dropdownlists. This i have done easily.
2) The next thing is to make the grid show data based on this values. this is its normal operation.
I thought that if i add the following code in page load would do the trick but it didnt. I tried all the events but no luck.I can get the dropdownlists to hold the value i want but the grid shows ALL records:
if (!IsPostBack)
{
if (Request.QueryString["ret"] != null)
{
string[] retvalues = Request.QueryString["ret"].Split('_');
Update_Search(retvalues);
dsTodo.SelectCommand = dsTodo.SelectCommand + Build_Where();
GridView1.DataBind();
}
}
The last 2 lines exist in the selectedvaluechange evnets on the dropdownlists and they work fine to filter the grid in normal operation.
You are setting the SelectCommand but you are not executing it. Do this:
dsTodo.SelectCommand = dsTodo.SelectCommand + Build_Where();
dsTodo.Select(DataSourceSelectArguments.Empty);
GridView1.DataBind();
That's assuming that the DataSourceID property of the GridView1 is set to dsTodo.
