Data Grid - Update Columns

[Ryan Ternier]

I'm playing around with DataGrids and the Edit columns ability.

I have a text area that can be anywhere from 1-8000 characters.

When I add the edit capabilities to this DataGrid it displays a single line
TextBox.

Is there anyway of getting this textbox to be multi line, and only 450
characters wide?

I've gotten the width using CSS, but can't fingure out how to make it a
"textarea"

Thanks!

Hi Ryan,

Are you using a template column? You should be able to configure a multiline
textbox inside that. You can said the character width using the Columns
attribute. Here's the idea:


<asp:templatecolumn>
<itemtemplate>
<asp:Label id="Label1" runat="server" Text='<%#
DataBinder.Eval(Container, "DataItem.stringvalue") %>'>
</asp:label>
</itemtemplate>
<edititemtemplate>
<asp:TextBox id="TextBox1" runat="server"
Text='<%# DataBinder.Eval(Container, "DataItem.stringvalue") %>'
TextMode="MultiLine" Height="55px" Columns="450">
</asp:textbox>
</edititemtemplate>
</asp:templatecolumn>

Thanks Ken!

That worked very well... however, whenever i try to update that field, I
can't find the actual textbox that contains the new data.

in the Cell that contains the Description (what I need the multiline for),
there are 3 controls. 0 being literal, 1 textbox, 2 literal.

I've also tried:

txtDescription = e.Item.FindControl("txtDescription")

And that still yeields the original textbox without the modifications I
made.

Any suggestions?
