RadGrid_ItemCommand doesn't fire on GridImageButton click event

[Covertix]

Hi,

I want to create my own expand/collapse functionallity for rad grid.
I have a GridImageButton column inside my grid with "+" button, and I want to chane it to "-" when the row is already expanded.
I tried to do it "OnItemCommand" event, but it doesn't fire.

Here is my code:

I create the grid inside a place holder on server side:

RadGrid grid = new RadGrid();

GridReport.ItemCommand += new GridCommandEventHandler(this.grid_ItemCommand);

GridPlaceHolder.Controls.Add(grid);

private void GridReport_ItemCommand(object source, GridCommandEventArgs e)

{

        if (e.CommandName == "Information")

         { 

                if (e.Item is GridDataItem)

                 {

                        GridColumnCollection gridColumns = e.Item.OwnerTableView.Columns;

                        GridDataItem myGridItem = (GridDataItem)e.Item;

 

                        if (gridColumns.FindByUniqueNameSafe("Information") != null)

                         {

                                ImageButton myRuleImageButton = (ImageButton)myGridItem["Information"].Controls[0];

                                 myRuleImageButton.ImageUrl =  "~/Images/Icons/collapse.png";

                         }

                 }

         }

}

 

private void GridReport_ItemDataBound(object sender, GridItemEventArgs e)

{

         if (e.Item is GridDataItem)

         {

                GridDataItem myGridItem = (GridDataItem)e.Item;

                if (gridColumns.FindByUniqueNameSafe("Information") != null)

                 {

 

                        ImageButton myRuleImageButton = (ImageButton)myGridItem["Information"].Controls[0];

                        myRuleImageButton.OnClientClick = String.Format("Click(" + myGridItem.ItemIndex + "); return true;");

                 }
        }

}

Column Creation:

buttonColumn = new GridButtonColumn();

buttonColumn.ItemStyle.BorderWidth = Unit.Pixel(0);

buttonColumn.CommandName = "Information";

buttonColumn.UniqueName = "Information";

buttonColumn.ButtonType = GridButtonColumnType.ImageButton;

buttonColumn.ImageUrl = "~/Images/Icons/expand.png";

buttonColumn.HeaderStyle.Width = Unit.Pixel(20);

buttonColumn.Resizable = false;

buttonColumn.Reorderable = false;

buttonColumn.Visible = true;

GridReport.MasterTableView.Columns.Add(buttonColumn);


     

Thanks!

Hello Tzach,

Please ensure that you are creating the RadGrid programmatically following the best practise in the help topic below:
http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html
Please take in mind the creation order in both case when the control is created in PageLoad and PageInit event.

Kind regards,
