Currently RadGrid supports strongly typed binding to a model and the use of OnCalling DataMethods, but requires additional non-documented code to get it to work correctly.

See forum post at http://www.telerik.com/forums/model-binding-selectmethod-defined-in-a-business-object#jyvrnG4qhEOdaXv_pBVt8g for the code requirements.

Request putting the ItemType and OnCallingDataMethods into the MasterTableView markup and eliminate the need to override the OnInit call. 

The markup would end up looking like:

<MasterTableView DataKeyNames="intOfficeId" ItemType="Models.OfficeModel" OnCallingDataMethods="grdAssignments_CallingDataMethods" SelectMethod="GetOffice" UpdateMethod="UpdateOffice" DeleteMethod="DeleteOffice" >

This would also pave the way to strongly bind the detail grid.

This should improve performance in this situation when client side data-binding can be used.

Misalignment issue in RadGrid with static headers and simple control's configuration appears in IE.

RadGrid filtering issue when RenderMode is set to Mobile and the grid is bind on the client

See the movie below:

This can be replicated in the online demo below when edit mode is set to Mobile:

There are more than 30 items (including task title) in RadGrid Task
I can't see Edit Template because my display resolution is not enough to show all Tasks.
I always get this problem with small resolution monitor.
Can you make it collapsible?
How do I go to EditTemplate? The task is not in the screen

In Telerik version 2016.2.607.45, the RadGrid Excel Like Filtering Context Menu Style is Broken. The width and alignment is not 100%. When I drop the older Telerik.Web.UI dll and corresponding Skins dll in my project, the issue is gone. I have attached two images, one from the latest release, and one from the older version. You can see how the latest versions style breaks and does not show the menu correctly. 

In radgrid, the excel style filtering shows a checkbox list of values to filter a column.  This has limited use on a date + time column of a grid, because such a list would show basically every grid row value in the list.  I can bind date only to the filter checkboxes to shorten that list, but if I apply a selected checkbox to filter then there will be no records returned.  This checkbox filtering needs to work with the grid column attribute EnableTimeIndependentFiltering (when it is filtering a datetime column) but it does not - that attribute only works with the datepicker calendar and text entry.   

When in batch edit mode, using standard asp.net validation controls will display the validation error within the cell, and expand the cell contents horizontally and possibly vertically as well.  This is a very ugly (and clunky) way to show validation messages in a batch edit mode.  

It would be nice if instead, we could set an grid attribute that specifies a row backcolor when validation fails for a row.  In addition, show that rows validation messages automatically in a tooltip or radtooltip as the user hovers the mouse over the row when it signifies the exception backcolor.  These messages could be assigned to a columns markup as an attribute.   

Another nice to have is to show a  section on the grid (perhaps under the header) that could display to alert the user when validation had failed.

The client-side KeyPress event is falling out of favor and the KeyDown even is being used more. Please implement an OnKeyDown event for the Grid, just like you currently have an OnKeyPress event

Workaround for the NextPrevAndNumeric mode is to set the AssociatedControlID of the label

	protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
	{
		if (e.Item is GridPagerItem)
		{
			GridPagerItem pager = e.Item as GridPagerItem;
			Label lbl = pager.FindControl("ChangePageSizeLabel") as Label;
			Panel pnl = lbl.Parent as Panel;
			RadComboBox combo = pnl.FindControl("PageSizeComboBox") as RadComboBox;
			lbl.AssociatedControlID = combo.ID;
		}
	}

	<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AllowSorting="True"
						AllowPaging="True" GridLines="None" Width="100%" OnItemDataBound="RadGrid1_ItemDataBound">
		<PagerStyle Mode="NextPrevAndNumeric" Position="TopAndBottom" PageSizeControlType="RadComboBox"></PagerStyle>
	</telerik:RadGrid>
			
	<asp:SqlDataSource ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
						ProviderName="System.Data.SqlClient" SelectCommand="SELECT CustomerID, CompanyName, ContactName, ContactTitle, Address, PostalCode FROM Customers"
						runat="server"></asp:SqlDataSource>

Th header context menu of the Grid gets closed on click (select/deselect a column) if the Grid is initially scrolled horizontally.

Steps to reproduce:
    1. Open the Live Demos solution for "UI for ASP.NET AJAX R1 2017" in VS2015;
    2. Open the page "UI for ASP.NET AJAX R1 2017\Live Demos\Grid\Examples\Functionality\Scrolling\scrolling\DefaultCS.aspx";
    3. Enable the HeaderContextMenu by setting EnableHeaderContextMenu="True" in the tag telerik:RadGrid;
    4. Disable the column freezing.
    5. Run the Demo and open the page "Grid\Examples\Functionality\Scrolling\scrolling\DefaultCS.aspx";
    6. Scroll the horizontal scrollbar of the grid to the right;
    7. Right click on the column header and pick the Columns from the context menu;
    8. Select or unselect any column, the Column Chooser will close by itself;
    9. Now, scroll the horizontal scrollbar of the grid all the way to the left;
    10. Right click on the column header and pick the Column Chooser from the context menu;
    11. Select or unselect any columns, the Column Chooser won't close by itself.

To overcome this issue you can do the following:

- For anchor links (a) implement onclick event with window.location.
- For submit buttons set UseSubmitBehavior property to false.

If the selection mode of the Grid is different than row selection, no cell of the detailed grid gets selected. The bug is introduced with version 2016 R3 SP1

Steps to reproduce:
1. Run the following demo locally  http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarative-relations/defaultcs.aspx

2. and add this configuration:
       <telerik:RadGrid ...>
            <ClientSettings>
                <Selecting CellSelectionMode="SingleCell" />
            </ClientSettings>

You would get something like

(([createddate] >= '01/08/2017,00:00:00') AND ([createddate] <= '14/08/2017,23:59:59'))

while you should get something like

(([createddate] >= '01/08/2017 00:00:00') AND ([createddate] <= '14/08/2017 23:59:59'))

so that the SQL syntax is valid.

RadGrid, does not send the FilterExpression to the SqlDataSource, however. It executes the SELECT statement and then filters the resulting data on its own. This works fine.

If you will be performing operations yourself, you could use a string operation before passing the filter expression. For example:

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
	if (!string.IsNullOrEmpty(this.RadGrid1.MasterTableView.FilterExpression))
	{
		if (this.RadGrid1.MasterTableView.FilterExpression.Contains("createddate"))
		{
			this.RadGrid1.MasterTableView.FilterExpression = this.RadGrid1.MasterTableView.FilterExpression.Replace(",", " ");
		}
		DataView dv =GetData("select * from [myTable] where ", this.RadGrid1.MasterTableView.FilterExpression);
                //where you would need to have something like (([createddate] >= '01/08/2017 00:00:00') AND ([createddate] <= '14/08/2017 23:59:59'))
		this.RadGrid1.DataSource = dv;
	}
}

Note that implementing such a change may break existing code that relies on the current syntax that contains the comma.

For Bug Report :

Note: We are using MM/dd/yyyy as Internal Date format to prevent issue while inserting or updating value.

Steps to reproduce:
When we use dd-MM-yyyy and yyyy-dd-MM Date DisplayFformat for RadDatePicker/RadDateTimePicker control as well as view mode in Radgrid Batch Edit mode it's render behaviour is inconsistent
1. When dd is less than or equal to 12 then while rendering in edit mode Month and Date is interchanged
2. When dd is greather than 12 then while rendering in edit mode Month and Date is rendered correctly.

Provide a simple interface to showcase exactly in what order the columns have been sorted in (ex. 1, 2, 3, etc in column header) - matching the functionality in Kendo UI Grid:

In some cases, inside the Grid table, the tfoot element is rendered before the tbody element. This causes some readers to read the footer before the body. 

A possible workaround is moving the tfoot after the tbody in the OnGridCreated event:

<script>
function OnGridCreated(sender, args) {
    var $ = $telerik.$;
    $('tfoot').each(function (index, item) {
        var $item = $(item);
        var $next = $item.next();
        if ($next[0]) {
            if ($next[0].tagName.toLowerCase() == "tbody") {
                 $item.insertAfter($next);
            }
        }
    });
}
</script>
