Using an ajaxified RadGrid (latest and greatest version) I have implemented a custom Command Template to facilitate add, edit, insert, update, and cancel actions based on demos here.

            
This works fine but does not work for editing or deleting if you are using a custom <ItemTemplate>.  I say this because as such it relies on a "selected" row or item in the grid. I have the code to select the row on the client side but cannot figure out how to display or enact the selected row when using the custom <ItemTemplate>.

So the questions are:

  1. How does the selected row strategy work with custom ItemTemplates?
  2. As an alternative, are there any examples of showing two small columns side by side with icons only for the AutoGenerated "Edit" and "Delete" columns instead of the default?

Thank you,

P.S.  Try posting a message with a title of "Custom <CommandTemplate> when using a custom <ItemTemplate>".  The server will not accept it.

Hello Reid,

RadGrid row selection works same way no matter what type of columns you have in your grid columns collection.

Regarding the auto generated edit and delete columns, try handling the grid PreRender event as shown below:

protected void RadGrid1_PreRender(object sender, EventArgs e)  
{  
    foreach (GridColumn column in RadGrid1.MasterTableView.Columns)  
    {  
        if (column.ColumnType == "GridButtonColumn")  
        {  
            (column as GridButtonColumn).ButtonType = GridButtonColumnType.ImageButton;  
        }  
        if (column.ColumnType == "GridEditCommandColumn")  
        {  
            (column as GridEditCommandColumn).ButtonType = GridButtonColumnType.ImageButton;  
        }  
    }  

Let me know if this helps.

All the best,

Hello Lana,

Thank you for responding.

I deployed the code you display below and the grid still shows the command columns as "Edit", "Delete" Links and not icons when the page loads.  After I click on one of the linkbutton commands and the MasterEditTemplate shows, the icons then show.  Do you know why they are not showing initially?

Hello Reid,

Can you try moving the sample code in RadGrid ColumnCreated event and see if it makes any difference?

Let me know how it goes.
