Edit Datagrid - show textbox and dropdown

[Anamika]

Hi All,
I have a problem trying to edit the data in a datagrid control.
I have 2 bound columns in the datagrid. I have added the following
code inorder to edit the data. I want it such that certain rows of
data when edited will bring the textbox control while certain other
rows will bring a dropdownlist from where i can select a value.

is it possible to do that in the SAME template column?
Any help will be much appreciated.

Thanks,
Anamika

It is possible, yes. First, you'd have to use a TemplateColumn instead
of a BoundColumn. To customize the editing interface, you need to use a
TemplateColumn, as discussed in this article:

Now, I assume you have some databound field that determines whether or
not a TextBox should be shown or a DropDownList. In the simplest case,
you could just toggle the Visible property based on this value.
Something like (untested):

<asp:TemplateColumn>
<ItemTemplate>
<asp:TextBox ... Visible='<%#
Convert.ToBoolean(DataBinder.Eval(Container.DataIt em, "ShowTextBox"))
%>' ... />

<asp:DropDownList ... Visible='<%# Not
Convert.ToBoolean(DataBinder.Eval(Container.DataIt em, "ShowTextBox"))
%>' ... />
</ItemTemplate>
</asp:TemplateColumn>

This assumes that the ShowTextBox database field is a Boolean and
indicates whether a TextBox should be shown (True) or a DropDownList
(False).

Hi Scott,
Thanks for the response. I went through your site before posting here.
I'll try toggling the controls during runtime like you suggested.

Thanks,
