.hasChanges() results in records flagged for Delete to not actually get deleted when .saveChanges() executes.
I found the same behaviour on a LiveDemo example that checks .hasChanges(): Grid - Binding to Telerik ClientDataSource
Steps to reproduce:
- Make any change to the first record, such as modifying the Contact Name.
- On the second record, Click the "x" under the DELETE column to mark it for delete.
- Click any column heading to sort. (This calls a UserAction event handler that calls .hasChanges())
- Choose to Cancel at the popup prompt.
- Click "Save changes".
- Monitor the browser console, you will find that webservice UpdateCustomers is called, but DeleteCustomers is not.
The SearchRow in RadGridView WinForms is extremely good.

How can we implement the same in ASP.Net Ajax RadGrid?
Hi,
In mobile and tablet device is very difficult increase and decrease the size of columns of RadGrid.
Is there any way this functionality can be improved?
Perhaps, Increasing the left/right border of the Column which can be grabbed for resizing would help easy this functionality.
The column headings read by JAWS are not great. I see that the rendered table headings have an aria-label attributes, but the text of these labels appears to match the DataField attribute of the grid column. Unfortunately, the DataField is often not the same as the human readable text displayed on the column header. This provides an inconsistent and sometimes confusing experience for screen reader users.
For example, if my data field is named something like full_name_with_title, but my column heading is actually "Full Name," the user will hear fullunderlinenameunderlinewithunderlinetitle, but we'd like them to hear "Full Name". All those underlines are confusing.
It would be much better if Telerik used the HeaderText attribute of the column instead of the DataField attribute. This would ensure that the presentational text and not the internal column names were read to the user.
A temporary workaround can be using the following OnGridCreated handler:
function OnGridCreated(sender, args) {
if (sender.get_enableAriaSupport()) {
sender.get_masterTableView().get_columns().forEach(function (col) {
var header = col.get_element();
var headerText = (header.textContent || header.innerText).replace(/^\s+|\s+$/g, '');
header.setAttribute("aria-label", headerText);
})
}
}

If AJAX is enabled for the RadGrid and re-ordering its columns, a JavaScript exception is thrown: "uncaught typeerror: cannot set property 'control' of undefined"
If paging is disabled and the PageSize is set to less than the number of records bound to RadGrid, client item templates are not all rendered correctly.
Example:
If PageSize is 10, and records bound to Grid are 15, then the first 10 records will have templates rendered correctly, while the rest of 5 records will not.
protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
if(e.CommandName == RadGrid.ExportToExcelCommandName)
{
// if there are items in edit mode, clear those
if(RadGrid1.EditIndexes.Count > 0)
{
RadGrid1.EditIndexes.Clear();
RadGrid1.Rebind();
}
// if insert item is present, cancel the insert form
if (RadGrid1.MasterTableView.IsItemInserted)
{
RadGrid1.MasterTableView.GetInsertItem().FireCommandEvent("Cancel", "");
}
}
}
We are still experiencing a problem with the RadGrid and JAWS when aria support is enabled. The JAWS form fields dialog (INS+F5) renders all elements of the grid on a single line.
Assuming the following configuration for RadGrid:
- RenderMode="Mobile"
- AllowSorting="true"
Testing using a mobile device (e.g. Chrome in Galaxy Nexus)
Test case 1:
If I click on middle of three dots Icon, then RadGrid opens the options menu
Test case 2:
If I click a bit below of the three dots Icon, then RadGrid does a sort on the column automatically
Unable to open "columns" sub-menu inside RadGrid's HeaderContextMenu on mobile devices. It does work on desktop PCs regardless of the OS.
Issue can be replicated starting with the version 2019 R1. Not present on previous versions (2017 and 2018 were tested)

Hello,
It would be nice to be able to clear the filter for each column as opposed to creating an external button to clear all filters. I was thinking of similar to below.
Requesting the improvement of this functionality to include scrolling.
Brief summary of the issue:
MultiCell selection uses a virtual marque tool to select items and does not include items that are out of view.
- Open your demo for Batch Editing: https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx
- Add a new row
- Enter values
- Click on x to delete
Expected: the row disappears.
Actual result: nothing happens.
I have a Telerik RadGrid, and there is a date column on the grid layout. The date format I am using to display date values is "dd/MM/yyyy". Then, I export that grid data to Excel file with GridExcelExportFormat.Biff type. The problem here is when I open the newly exported Excel file, the date format is changed to "MM/dd/yyyy".
I want to keep displaying my date format "dd/MM/yyyy" in the Excel file after exporting the grid data.
Issue seems to happen with RadGrid with Bootstrap Skin, RenderMode Lightweight when RequireFieldValidator is enabled in combination with Batch Editing.
Unexpected look (Bootstrap skin):
Other skins seems to have it right.
Expected look (Default skin):
Expected look (Silk skin):
If the Page culture is set to anything other than "en-US", RadDatePicker in the HeaderContextMenu will loose the correct format and swaps the Day with the Month after filtering.
