Current RadGrid only has headers/header templates for column headers. The only way to have headers for each row would be to manipulate the grid data and adding the header for each row into the grid data itself. And if we wanted to group the row headers is another round of manipulating the grid data and also manually merging the cells. Is it possible to have to have it as a feature of the RadGrid just like column groups and column headers to simplify the task? example of the final output ->

We used Telerik in our application. The network team reported a spam in it.
Using Telerik grid with SortExpression in telerik:GridTemplateColumn, has been reported as high priority network issue.
Issue name : Ajax request header manipulation (DOM-based)
Recorded the issue in below snippet of responce.
onclick="Telerik.Web.UI.Grid.Sort()"
Please let me know if you have any suggestions.!!!
The horizontal line just above the group header:
Reproduction steps:
- For RadGrid set RenderMode="Mobile" and EnableHeaderContextMenu="true"
- For Grid Column set Groupable="false"
- Try to group by the non-groupable column - http://somup.com/cYirQb6fqR

To reproduce the issue enable RowSelect and RowsDragDrop ClientSettings, and attach OnRowDropping event listener

<Selecting AllowRowSelect="true" />
<ClientEvents OnRowDropping="function() {alert('RowDrooping event fired!');}"/>
</ClientSettings>
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.
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".

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.
Code to reproduce the problem:
<style>
html, body, body > form {
height: 100%;
padding: 0;
margin: 0;
}
</style>
...

Replicated when the ClickToOpen is enabled:
protected void Page_Load(object sender, EventArgs e)
{
RadGrid1.HeaderContextMenu.ClickToOpen = true;
}
WORKAROUND: Loading the following script under the script manager
<script>
var original = Telerik.Web.UI.GridColumn.prototype._onContextMenuItemClicking;
Telerik.Web.UI.GridColumn.prototype._onContextMenuItemClicking = function (sender, args) {
original.call(this, sender, args);
var item = args.get_item();
var itemValue = item.get_value();
if (itemValue == "FilterList" || itemValue == "FilterMenuContainer" ||
itemValue == "AggregatesContainer" || itemValue == "FilterMenuParent" || itemValue == "ColumnsContainer" ||
(Telerik.Web.UI.RadMenuItem.isInstanceOfType(item.get_parent()) && item.get_parent().get_value() == "ColumnsContainer")) {
if (sender.get_clickToOpen()) {
args.get_item().open();
}
}
}
</script>
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.
