get content of text boxes dynamically created

[tarscher]

Hi all,

I create a set of text-boxes based on user input:

for (int i = 0; i < Convert.ToInt16(keywordsDropDownList.Text);
i++)
{
myTextBox = new TextBox();
myTextBox.Columns = 5;
myTextBox.ID = "parameterTextBox"+Convert.ToInt16(i);
myTextBox.TabIndex = (short) (i+1);
buttonPlaceHolder.Controls.Add(myTextBox);
}

The text boxes are followed by a button that, when clicked, should get
the content form the text boxes and put em in a database. How can I get
the content from teh text boxes?

I cannot use
someVar = parameterTextBox0.text
since it is not known

Thanks in advance
Stijn

But you can use Page.FindControl

TextBox tb = (TextBox)Page.FindControl("parameterTextBox0");

Stijn,

buttonPlaceHolder.FindControl ("parameterTextBox1") as TextBox

should do.

Thanks for the reply. i haven't made it work yet though. It seems that
FindControl can't find the textbox since null is returned. The
textboxes are placed inside a view (and multiview) and then inside a
placeholder (suing a masterpage). Maybe this is the reason why null is
returned?

Stijn

Hi all,

I tried the findcontrol with textbox I added via the editor but that
also returned a null. I used Page.findcontrol(id) and just
findcontrol(id).

Someone has an idea what I'm doing wrong?

You need to call FindControl on the control that directly contains the
control you are trying to find. Did you try my suggestion

buttonPlaceHolder.FindControl ("parameterTextBox1") as TextBox ?
