Change Text of Textbox inside Template

DarkForce · June 17th, 2007, 02:54 AM

Hi,

I have a Detailsview and a Textbox inside a Templatefield.
I try to access the Textbox in the %%%.cs Data file but i cannot.
Should look like

TextBox1.Text = "Hallo";

Hi there,

No, you can't access these controls directly. The DetailsView is a container control that contains these individual controls. Since you can potentially have more than one DetailsView on a page, the DetailsView must ensure that each TextBox and other controls have a unique name.

Depending on when and where you use this code, you can try this:

TextBox myTextBox = (TextBox) DetailsView1.FindControl("TextBox1")
myTextBox.Text = "Hallo";

This code "finds" the TextBox inside the DetailsView and then sets its text.

Hope this helps,

Imar

Using JQuery/JavaScript, is it possible to access properties of controls which reside inside EditItemTemplate?

Code:
