When trying to batch edit cell values of the Grid via e.g., RadEditor (GridHTMLEditorColumn or RadEditor in EditItemTemplate of GridTemplateColumn) the cell value always result to a plain text. 

In GridTableView.cs, you provide a function
 protected virtual GridTableView CreateTableView() (Line 7828).
This function can be overloaded to return derived classes from GridTableView.

But, this is not overloadable completely. Because you create a GridTableView directly in protected void BuildDetailTablesFromDataSource() (Line 8808), too.
There you would have to call a virtual creator function, too.

This is necessary, because I have a lot of Trouble with your DataBind which I was able to fix with an overload. It is much to hard to make this bug visible for you, I really tried to do so already, but I had to fix this that way, because your GridTableView without my derivation fails in our szenario.

The call stack for that problem, I'd had to fix, is always like:
Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IndexOutOfRangeException: Cannot find column CheckSum.

In that, your DataTableView gets an invalid sort Expression string. Therefore, I overwrote DataBind.

But this is not possible in all cases, if you create GridViewTable() objects on your own.

Best regards

System.ArgumentOutOfRangeException
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

This error seems to happen if there is a GridTemplateColumn that has the Exportable property set to False.

Have built-in option to do LIKE filtering on grids.

I have added Listview in Header template in Template column, its showing the data on the grid as expected. When I am exporting to Excel or PDF its not exporting the header. Header you see in headertemplate.jpg is not exporting to PDF

Thanks

Using CommandItemTemplate (Grid - Command Item) for Editing DetailTable records and selecting an item after filtering or from another page, one item from the first page is put for editing instead. Open the attached GIF animation (EditSelectedEditWrongItem.gif) to see it in action.

Currently the workaround we offer is to handle the EditSelected command manually for all the DetailTables Except for the Master.

Grid markup:

        <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="100%" PageSize="3"
            OnItemCommand="RadGrid1_ItemCommand"
            OnDetailTableDataBind="RadGrid1_DetailTableDataBind"
            OnNeedDataSource="RadGrid1_NeedDataSource">
            <MasterTableView Name="MasterTable" AutoGenerateColumns="true" DataKeyNames="OrderID">
                <DetailTables>
                    <telerik:GridTableView Name="ChildTable" DataKeyNames="OrderID" AutoGenerateColumns="true" CommandItemDisplay="Top">
                        <CommandItemTemplate>
                            <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" CssClass="btn btn-default">Edit Selected</asp:LinkButton>
                        </CommandItemTemplate>
                    </telerik:GridTableView>
                </DetailTables>
            </MasterTableView>
            <ClientSettings>
                <Selecting AllowRowSelect="true" />
            </ClientSettings>
        </telerik:RadGrid>

C# - ItemCommand

    protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    {
        // Logic applies for all the tables (detail tables) which are not named "MasterTable"
        if(e.Item.OwnerTableView.Name != "MasterTable" && e.CommandName == RadGrid.EditSelectedCommandName)
        {
            e.Canceled = true;

            GridTableView detailTable = e.Item.OwnerTableView;

            if (detailTable.OwnerGrid.SelectedIndexes.Count == 0)
            {
                return;
            }

            foreach (GridDataItem selectedItem in detailTable.OwnerGrid.SelectedItems)
            {
                selectedItem.Edit = true;
            }

            detailTable.Rebind();
        }
    }

VB - ItemCommand

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As GridCommandEventArgs)
    If e.Item.OwnerTableView.Name <> "MasterTable" AndAlso e.CommandName = RadGrid.EditSelectedCommandName Then
        e.Canceled = True
        Dim detailTable As GridTableView = e.Item.OwnerTableView

        If detailTable.OwnerGrid.SelectedIndexes.Count = 0 Then
            Return
        End If

        For Each selectedItem As GridDataItem In detailTable.OwnerGrid.SelectedItems
            selectedItem.Edit = True
        Next

        detailTable.Rebind()
    End If
End Sub

I skipped the 3rd quarter 2016 update (2016.3.1027) for my copy of Telerik UI for ASP.NET.AJAX, since we were in code lock down at that time. 

 Later i installed the 4th quarter version (2016.4.1021.0)

Now, I still get a notice to install the previous version  (2016.3.1027) that I skipped.

That's annoying, and probably not possible. Right?

Is there anything we can do about this situation?

Thanks in advance

Currently the Width of the Edit controls inside the inline Edit form of the Grid can be set only in pixels. In order to be able to implement a responsive layout the developer has to be able to set the width of these controls in percentage.

When virtualization is enabled for RadGrid, NeedDataSource is called at every Post back with RebindReason = ExplicitRebind, regardless of the event target.

Steps to reproduce:

RadGrid filter command is not triggered for strings containing "and" word.

Video: https://www.screencast.com/t/j649UvPQ3z6

Steps to reproduce:
Filter by "SUNBAY AND LEONA A" in the following demo:
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/excel-like-filtering/defaultcs.aspx

As a temporary workaround you can use Template column with a DataField set.

Alternating Row style of RadGrid is not applied when using Bootstrap skin.

Steps to reproduce:
For all other Skins these approaches work:
        div.RadGrid tr.rgAltRow {
            background-color: aqua;
        }

Or:
 <AlternatingItemStyle BackColor="Aqua" />

The reason probably is because there is >td directive built-in, which needs to be overridden manually in order for the styling to take effect (this works):
        div.RadGrid tr.rgAltRow > td {
            background-color: aqua;
        }


A possible workaround for this issue is available in the following forum post:

RadGrid GridDateTimeColumnEditor is unable to process data of type TimeSpan if PickerType is set to TimePicker.

As a workaround, a GridTemplateColumn can be used with a TimePicker inside EditTemplate

<telerik:GridTemplateColumn>
	<ItemTemplate>
		<%# Eval("Field") %>
	</ItemTemplate>
	<EditItemTemplate>
		<telerik:RadTimePicker ID="RadTimePicker1" runat="server" SelectedTime='<%# Bind("Field") %>'></telerik:RadTimePicker>
	</EditItemTemplate>
</telerik:GridTemplateColumn>
