Adding "delete" functionality in DataGrid - without a ButtonColumnthe user to click a "delete" button in each row of the datagrid to delete records. I originally used a <asp:ButtonColumn> for this and gave it a CommandName attribute. This worked great. However, the client wants to have a popup when they click on the delete button. So now I'm thinking that I have to create a javaScript function and instead of using an <asp:ButtonColumn>, I'll have to use an <asp:TemplateColumn> with an embedded <asp:button> inside of the item template. In this button I'm imagining I'll be able to do an onclick javascript event handler, but I'm not sure how to do this. I'm unsure how to create this type of functionality. The important piece is being able to pass the data for the entire row, from which the delete button was clicked, to the javascript function. This was easily done with the button colum because the _ItemCommand event handler for the datagrid took the input: DataGridCommandEventArgs, which had the data for the entire row. Any thoughts? Your help is greatly appreciated. -- PK9 You can still keep the delete button but change deleting
function to collect data and save data to SessionState. Then popup delete page, Response.Write("<script>open ('delete.aspx')</script>"). In delete page, retrieve data from SessionState.

to deal with another aspx page and session variables. I found my answer on the following website. This shows examples to do it with a buttoncolumn and an itemtemplate column!

ItemTemplate + button. Suppose your delete button (ButtonColumn) is the first column in the datagrid, just add some code in datagrid_ItemCreated event: switch (e.Item.ItemType) { case ListItemType.Header: case ListItemType.Footer: case ListItemType.Separator: case ListItemType.Pager: return; default: break; } LinkButton btn = (LinkButton)e.Item.Cells(0).Controls(0); btn.Attributes.Add("OnClick", "confirm('Are you sure you want to delete this record?');") That's it.
