Grid Sorting Focus Issue

[Swamy]

Hello,

I have a rad grid with property AllowSorting="true". I did set my sort expressions for all my columns. When i sort the columns it is working fine. Now i want to place the focus on the column link which is sorted now or on the asc/desc image button. Please advice me on this.

Thanks,
Syam.

Hello Swamy,

You could try the following approach:

<ClientEvents OnCommand="gridCommand" />

<asp:HiddenField ID="HiddenField1" runat="server" Value="" />

  JavaScript:

function pageLoad() {
    var value = $get("<%=HiddenField1.ClientID%>").value;
    if (value != "") {
        $get(value).focus();
        $get("<%=HiddenField1.ClientID%>").value = "";
    }
}
function gridCommand(sender, args) {
    if (args.get_commandName() == "Sort") {
        var masterTable = sender.get_masterTableView();
        var column = masterTable.getColumnByUniqueName(args.get_commandArgument());
        var ascIcon = $telerik.findElement(column.get_element(), "SortAsc");
        var descIcon = $telerik.findElement(column.get_element(), "SortDesc");
        if (ascIcon.style.display != "none") {
            $get("<%=HiddenField1.ClientID%>").value = ascIcon.id;
        }
        else if (descIcon.style.display != "none") {
            $get("<%=HiddenField1.ClientID%>").value = descIcon.id;
        }
     }
  }

I hope this will prove helpful.

Hi Eyup,

Thanks for the suggestion. I followed your approach and got the following error.

"The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."

Thanks,
Swamy.

Hi Eyup,

Finally i am not getting error now. But the value of ascIcon.style.display and descIcon.style.display
 is always none and so the hiddenfield value is not being set. Please advice me on this.

Thanks,
Swamy

Hello Swamy,

For the handled error, you will need to wrap your JavaScript code in RadCodeBlock as suggested in the following article:
http://www.telerik.com/help/aspnet-ajax/ajax-radscriptblock-radcodeblock.html

Could you please enable your script debugger ( FireBug for instance ) and verify that you are successfully accessing the icons and the hidden field?

Hi Eyup,

Thanks for the solution on handle error. I wrapped the script in RadCodeBlock and now everything is working as expected. I have changed my approach on this for time being but I will check it this resolves my sorting focus issue and update you at a later point of time. Also will this work with paging as well?

Thanks,
Swamy.

Hi Swamy,

It should work as expected. Of course, you will need to implement it according to your specific scenario.

All the best,
