Add button to child in RadGrid

[Hugo]

Hello,

I am evaluating the product, and I have a question.

I have a grid with a parent/child structure

I need to add a button on each child row.

I fill the grid using a run time defined dataset.

I can add a button to the parent using the configuration wizard. So when I bind the dataset to the grid, the button shows together with the parent datatable columns defined in the server.

But when I try to add the button to the child it doesn't work. Only the columns defined in the child datatable appear.

Any help will be greatly appreciated.

Thanks,

Hugo

Hi Hugo,

There are a couple of ways that you can add a button to the child items.

1. Add a GridButtonColumn in the markup of the detail table. More about column types you can find here.
2. Using OnItemCreated event to dynamically add the button in a template column from the code-behind:

   protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
       {
           if (e.Item is GridDataItem && e.Item.OwnerTableView.ParentItem!=null)
           {
               GridDataItem item = e.Item as GridDataItem;
               Button btn = new Button();
               btn.ID = "SomeId";
               btn.CommandName = "SomeCommandName";
               item["TemplateColumn"].Controls.Add(btn);
           }
       }

3. You can also add the GridButtonColumn using the configuration wizard(see the attached image). Please note that when adding the button you would have to set the CommandName.

Let me know if I could assist you further.
