With no filtering applied, the filter menu still highlights the filter-function defined in the CurrentFilterFunction property of the column.

I issue is replicated consistently with the following simple setup, when the page is scrolled so the grid is on the top and right-clicking the column, to open the menu 

<div style="height: 200px"></div>
<telerik:RadGrid ID="RadGrid2" runat="server" AllowFilteringByColumn="true" EnableHeaderContextMenu="true">
</telerik:RadGrid>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        RadGrid2.DataSource = Enumerable.Range(1, 3).Select(x => new { ID = 1, Desc = "Some text" });
        RadGrid2.DataBind();
    }
</script>
<div style="height: 4000px"></div>

Hi,

Without using radFilter to setup multiple filters before applying RadGrid can only be filtered one column at a time. Can a button be added to the Grid when filtering is applied that when Clicked will filter the Grid based on all of the column filter selections that a user selects?

Thanks,

Hello @support!

Did you observe the behavior, that Firefox (v71.0 64bit) does not turn the rad grid into edit mode, whereas IE11, Edge, Chrome (v78) perfectly work ok on the same grid?

Clicking the edit stencil button only makes the two arrows below rotate for some seconds, but nothing happens. What could that be?

Video Demo is attached.

Thank you,
Alexander 

See online demo:

https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

Steps to reproduce (seen in Chrome and Edge):

- Click the "x" on the 2nd to last record on page 1 to mark it for deletion  (Click "OK" at the prompt)

- Click "Add new record" button

Observe:

 - the record marked for deletion moves up by one record (but fortunately it appears the correct record will actually get deleted upon Saving)

 - a blank new record is creating correctly

If you repeat this procedure but choose a different record for deletion you can see it is functioning correctly.

I am seeing the same behaviour in my own project.

.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?

When page scrolling is enabled and scrolling down the page, the row context menu of RadGrid rows do not open at a correct position.

Demo: Video Recording

Testing conducted in Safari 13, MacOS

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.

I would assume that Delete and Edit columns should never be exported to excel to begin with, especially if HideStructureColumns="true".

If the HideStructureColumns is hiding something else, it would be nice to have another flag that would control showing/hiding Edit/Delete columns. 

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

Hello, 

There is an issue with Classic render mode Grid when grouping is enabled. The width of the grouping is incorrect and some of the icons are wrapped on the next row.

If using Frozen Columns with MultiHeaders, where one column has many headers while the other fewer. Each header in a column occupies some space and they get hidden, this will cause the upper (header) portion of the Grid to change its size. With that, the scrollbar will move away from the mouse position and causes the scrolling jump back and forth resulting in flickering.

Demo video of the issue: RadGrid FrozenColumns Flickering Header. The video can be found in the attachments as well.

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)
