Answer 1

Put a button or any other control you like, and set for this button the command name property equal “delete” for example, put any id in the command argument property to know which row you will delete, and in the repeater ItemCommand event check for this command name then do the delete function.

Example:

<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
    <ItemTemplate>
        <asp:LinkButton ID="LinkButton1" CommandName="Delete" OnClientClick="javascript:if(!confirm('Delete this information? this will delete permanently'))return false;" CommandArgument='<%#Eval("EntityID") %>' runat="server">Delete</asp:LinkButton>
    </ItemTemplate>
</asp:Repeater>

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "Delete" && e.CommandArgument.ToString() != "")
    {
        // DoDelete then rebind
    }
}

Delete Code will be something like this:

Dim connectionString As String = ConfigurationManager.ConnectionStrings("UploadConnectionString").ConnectionString 

Dim adapter As New SqlDataAdapter("DELETE FROM FileM where id=" & e.CommandArgument.ToString(), connectionString)
