Inserting with EditTemplate

[Jocelyn]

Well, I have an EditTemplate that I bound some data to some RadControl. The problem is when I try to insert, I got errors on bound item because they are DBnull. So how can I have the template with empty control while inserting?

for starters, remove any DataType parameters
on numeric text boxes, change the Value= to DBValue=

Thanks Marianne.

I already use DbValue. I got this error on non-rad controls like Checkbox.

What can I do to solve this?

Hello Jocelyn,

The reason for this error is that your grid instance can not bind a value for the newly inserted item through the Eval()/Bind() syntax. A solution would be to preset the default value of the control(s) when binding to a grid item on the RadGrid.InitInsertCommandName command.

ASPX:

telerik:GridTemplateColumn HeaderText=""  UniqueName="StartCheckboxColumn" >
        <ItemTemplate>
            <asp:CheckBox ID="StartCheckbox" runat="server"  AutoPostBack="true" Checked='<%# Bind("START") %>' />
        </ItemTemplate>
    </telerik:GridTemplateColumn>

C#:

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
    if ((e.CommandName == RadGrid.InitInsertCommandName))
          {
        e.Canceled = true;
        //Prepare an IDictionary with the predefined values
        System.Collections.Specialized.ListDictionary newValues = new System.Collections.Specialized.ListDictionary();

        //set initial checked state for the checkbox on init insert
        newValues("START") = false;

        //Insert the item and rebind
        e.Item.OwnerTableView.InsertItem(newValues);
    }
}

Hope this helps,
Princy.
