RadFileExplorer Grid column sorting

[Rajeev]

Hello All,

I have a RadFileExplorer in our application which is created dynamically. The grid has two bound columns for which we have to enable column sorting. I have registered the GridSortCommandEventHandler while creating the Grid but the grid is not triggering the Sort event.

radFileExplorer.Grid.ID = radGridViewName;

radFileExplorer.Grid.AllowSorting = true;  
radFileExplorer.Grid.ItemDataBound += new GridItemEventHandler(radFileExplorer_ItemDataBound);  
radFileExplorer.Grid.SortCommand += new GridSortCommandEventHandler(radFileExplorer_SortCommand);  
radFileExplorer.TreeView.NodeClick += new RadTreeViewEventHandler(treeView_NodeClick);

Below is the code written for radFileExplorer_SortCommand event. The below event is not getting invoked on click of the column header.

void

radFileExplorer_SortCommand(object sender, GridSortCommandEventArgs e)  

{

string sortDir = "ASC";  
DataView dv = new DataView(Documents);  
string viewStateKey = "sortDirection" + e.SortExpression;  
if (ViewState[viewStateKey] != null)  

{
sortDir = ((string)ViewState[viewStateKey] == "ASC") ? "DESC" : "ASC";  
}

ViewState[viewStateKey] = sortDir;
dv.Sort = e.SortExpression + 

" " + sortDir;  
SortExpression = dv.Sort; 
GridView docListGrid = (GridView)this.FindControl(radGridViewName);  
if (docListGrid != null)  
{

docListGrid.DataSource = dv;

docListGrid.DataBind();

}

}

This is quite urgent and any help would be appriciated.

Many thanks in advance.

Regards
Rajeev

Hi Rajeev,

The grid component of RadFileExplorer is using client-side binding, that is why the SortCommand event is not fired. You can assign handler to the grid's ClientCommand client-side event to apply custom logic during the event, e.g.:

<telerik:RadFileExplorer ID="RadFileExplorer1" runat="server" OnClientLoad="OnClientLoad">
    <Configuration ViewPaths="~/" />
</telerik:RadFileExplorer>

<script type="text/javascript">
    function OnClientLoad(oExplorer, args)
    {
        var grid = sender.get_grid();
        grid.add_command(sortCommandHandler);

    }

    function sortCommandHandler()
    {
        if (args.get_commandName() == "Sort")
        {
            //add custom code here
        }
    }
</script>

I hope this helps.
