There is some undesirable behavior that has been discovered by our users regarding APS.Net RadGrid when filtering with the checkbox list.  I have seen that the issue also happens on the Telerik Demo page found here and will use it as the example: https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/basic-filtering/defaultcs.aspx

If you go to the last demo on that page (Filtering with Client-Side Binding) select the filter for Country.  When the checkbox items appear, click on an item, however do not click on the checkbox.  What happens is the dropdown closes and nothing happens.  The demo however is for cliet side binding which is does not postback to the server.  Our control is handled on the server-side so when this happens a request is sent and the user is presented with the loading circle which makes the user think something is actually happening, yet it is not.

I suggest that the behavior of clicking on an item, outside of the checkbox, checks the box and keeps the list open.

At the least, there should be no request that is sent to the server as the box was not actually checked with the current behavior.

I have attached an image with a red 'X' on where a user may click to reproduce this behavior.

When Exce-Like filtering is enabled for the Grid, the Accessibility Validation Tools detect errors such as "A button is empty or has no value" and "Missing form label".

Reproduction steps:

  1. For RadGrid set RenderMode="Mobile" and EnableHeaderContextMenu="true"
  2. For Grid Column set Groupable="false"
  3. Try to group by the non-groupable column - http://somup.com/cYirQb6fqR

Steps to reproduce the error.

Create a ClientDeleteColumn with CommandName="Delete" and wire up the onCommand client-event to RadGrid.

<telerik:RadGrid ID="RadGrid1" runat="server">
    <MasterTableView>
        <Columns>
            <telerik:GridClientDeleteColumn CommandName="Delete" ButtonType="LinkButton"></telerik:GridClientDeleteColumn>
        </Columns>
    </MasterTableView>
    <ClientSettings>
        <ClientEvents OnCommand="OnCommand" />
    </ClientSettings>
</telerik:RadGrid>

The event handler does not need to do anything.

function OnCommand(sender, args) {
}

Bug report

When I use TimePicker in GridDateTimeColumn it works fine in a normal browser but fails on mobile with the following error "Value must be 00:00 or earlier"

This works fine from Firefox, but when I use a mobile browser I get the following error "Value must be 00:00 or earlier" or "Value must be 12:00 AM or earlier".

If AllowPaging, AllowScroll and UseStaticHeaders are set to true, then there will be 2 empty <th> elements

workaround: 
    <ClientSettings>
...
        <ClientEvents OnGridCreated="OnGridCreated" />
    </ClientSettings>

<script>
    function OnGridCreated(sender, args) {
        var emptyth = $telerik.$(sender.get_element())
            .find("th").filter(function (ind, item) { return item.textContent == "" });
        // alert(emptyth.length)
        emptyth.append("<span style='display:none'>Hidden empty table header</span>")

When using iPad touch to open the header context menu of a grid column, an immediate postback prevents the opening of the menu when the RadGrid is in Mobile RenderMode. The reason is that this action gets recognized as dragging when AllowDragToGroup is enabled.

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)

In a GridDateTimeColumn I have some value data with milliseconds like "2018-09-24 18:05:21.057"

Filtering with the milliseconds returns no results.

Then I remove milliseconds part "2018-09-24 18:05:21"

Filtering without that will return results.

Even with the EnableTimeIndependentFiltering property set to True, the milliseconds are not ignored, and the filtering mechanism doesn't find the records.

Issue #1. When the Grid is not having any records (i.e. when the grid is initialized for the first time), if we define the Detail Item Template than the item template is shown 10-11 times. 

Issue#2: When we have the pagination enabled in the grid and the records are fully filled on the first page and suppose the second page is half-filled with records, then in this scenario On the second page even the records of the first page are hidden but the data item template for those rows are visible which is not correct. Screenshot is attached.

Issue #3: The same scenario is happening when we searched the grid first with 10 records and then we search for 2 records, In this case also 8 records will be removed but there data item templates will still be visible on the grid.

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
