Manually showing sort Icon

[Mrutunjaya Das]

Hi All,

I have a telerik grid and sorting works fine with it. The problem arises when I try to refresh the page when the grid is sorted. The sort icon which appears on the column header of the grid is missing , where as the grid contains the sorted data.

Someone please tell me how to manually show the arrow Mark from the code behind.

Thanks

Hi Mrutunjaya,

I tried to replicate the described issue in this example but to no avail. Please give it a try and let me know what is the difference in your scenario.

Hi Pavlina,

Thank you for the reply. Your example is working fine. There is some difference between yours and mine. You are using the Datasource="sqlDataSOurce1" in your grid , where as in my case I am handling onNeedDatasource event. So data feeding to the grid is done from the code behind of my page. 

I am not sure, but what I am guessing is showing of sort icon is handled internally in telerik grid when "OnSortCommand" event is fired. In my case page refreshing doesn't invoke the handler of the above event. So I need to somehow manually show the sort icon.

What I am doing is , I am including the below line in my page_Load

this.MyGrid.Columns.FindByDataField("ColumnName").ShowSortIcon = true;

Which doesn't seem to be affecting the grid.

Will appreciate some light on this.

Thank You

Hello Mrutunjaya,

Can you paste your aspx and code-behind (please, use the code-formatter tool of the ticket editor). We will test it locally and advise you further.

Thanks.

                                <div>
                                    <asp:Label ID="label1" runat="server" Text='<%# Highlight("" + DataBinder.Eval(Container.DataItem, "Id"),"<span class=\"highlightRed\" style=\"text-decoration:underline;\">", "</span>")%>'></asp:Label>
                                </div>
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>
</MasterTableView>
</telerik:RadGrid>


I have handled every event in code behind. But when I refresh the page I have a flag that tells me
whether the grid contains the sorted list or not. I just need to know how to show the arrow button
for the sorted column from code behind. Right Now what I am using is 

this.MyGrid.Columns.FindByDataField("ID").ShowSortIcon = true;

Which isn't working. If you need me to provide any of the event handler, Please let me know.

Thanks
