Finding controls inside a details view
I am building a website using ASP.NET 2.0 and Visual Studio 2005.
I have a page (called default.aspx) which has a SqlDatasouce in it, a FormView, and a DetailsView inside of the FormView.
Inside the detailsview, there are two columns (both are templateitems). One contains a webusercontrol (called "mywebusercontrol") and one is a textbox (called "textbox1")
The webusercontrol needs to know about the textbox, because it uses the value of the textbox to do other processing. So I made a property in the webusercontrol called "TargetTextBox", of type "Textbox". Now I need to initialize that property when the page loads.
But in the Page_Load even for my default.aspx page, I can't see any of these controls I created. The intellisense doesn't show the WebUserControl or the Textbox. The only thing I can see is the FormView, but I can't see anything inside of it.
How do I initialize this TargetTextBox property of the WebUserControl1 object to be equal to a reference to the TextBox1 object?

addition to informaniac:
that's right you have to use FindControl, but you have to do it within the event ItemDataBound of this FormView
private void ..ItemDataBound(object sender,
System.Web.UI.WebControls.
{
//inteligense willhelp you with this method, I dont have my code right now, you might wanna check the syntax...
if (e.Item.ItemType == ListItemType.Item ||
e.Item.ItemType == ListItemType.AlternatingIt
{
TextBox txt1 = (TextBox)e.Item.FindContro
ctrl.TargetTextBox = txt1.ID;
...
Hope this help

The details view and formview do not have an "ItemDataBound" event.
informaniac:
The variables get set to "Nothing" when I call the FindControl method, no matter what I do.
I have tried the suggested code in the Page_Load event, Page_PreRender event and FormView1_DataBound event, to no avail.

// note: the webusercontrol is called Field_TaxDropdown
// The textbox is called txtExpense
// The property in the webusercontrol I'm trying to set is called "SourceDataTextBox"
Dim ctrl As Field_TaxDropdown = CType(FormView1.FindControl("Field_TaxDropdownGst"), Field_TaxDropdown)
Dim txt1 As TextBox = CType(FormView1.FindControl("txtExpense"), TextBox)
ctrl.SourceDataTextBox = txt1
I am back to office now ^^
SOrry I was confusing myself with the ListVIew and didn't realize that you use FormView, have you fixed your problem, or do you need further assistance, I think the suggesion of informaniac is right.
Make sure you called it after the FormView has been bounded. try ItemCreated event now?
