I'm using Visual Web Developer 2010. I placed a TextBox control on the form and want to be able to refer to it in the CodeBehind. Other controls like the DropDownList and the FormView are referenceable in CodeBehind, but the TextBox is not. I have RUNAT set to SERVER.
View 6 RepliesI have a page with an iframe on it in which I load another page.On this iframe page I have some textboxes above eachother.When the first textbox is filled with a code the textchanged event is called nd the code is checked with the database.After the code has been changed to the right one (if needed) I want the focus to go to the next textbox.
So at the end of the event I do: Page.SetFocus(txtbox2)ut after the postback refresh, the focus is gone.
I have also put the control to be focused in a session variable and then in the page_load event I set the focus to the control in the session variable, but still no focus on the textbox.How can I put it on the 2nd textbox?all is done in the Iframe page codebehind.
I need this focus because the two textboxes are filled via bar code reader and after the scan an "enter press" is done automatically and to be able to allow two scans after each other this focus change is needed.
I have a detailsview with three textboxes as itemtemplates. Each for holding a different date. To avoid the option of users entering invalid values the textboxes are disabled and the user can use a calender control to fill the dates. Because the textboxes are disabled I added a linkbutton to empty a date, if the user decides to clear it.
Asp:

In the code behind is the following for linkbutton on click:

Now, the problem is that no matter which linkbutton a user clicks all three textboxes are cleared/emptied. Why?

I am able to find the controls of all of these Lables and TextBoxes accept the edateTB. This is strange to me because it is in the same view as the sdateTB. So why would edateTB return NULL when I try to use FindControl on it and sdateTB return the correct control?
