View 2 RepliesI have created a master page for website layout in my project. I have used a linkbutton control to trigger between Login/Logout functionality but when I click on this control the underlying click event handler is not being executed anyway.When I click on this control, the page pointed by its PostBackUrl property is open which should probably occure after its click event hander have been executed.

I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.

View 1 RepliesI have a custom ascx user control on my page that includes a dropdownlist. There is an onSelectedIndexChanged event handler that is connected to this dropdownlist. The first time the user selects a value, the page does a postback and the logic executes correctly. However, if the user then goes to change their selection, the event handler does not get triggered.

Why are some controls initialised and others not? How do I get around this if I'd like to update the Text property on currentPageLabel?
Update:
I've placed breakpoints all the way through the page life cycle and found that nextButton and currentPageLabel are never initialised. The breakpoints were placed at OnLoad, CreateChildControls, goButton_Click, OnPreRender, Render and OnUnload.
I have a User Control which consists of a TextBox with a few extras, but for purposes of this example just assuming it's a plain TextBox will be sufficient. I am calling this User Control from a Web Form and would like to be able to use a RequiredFieldValidator that basically would function the same as if I used it on a TextBox on the web form. How do I configure my User Control to handle this?

View 3 RepliesI've been working with ListView for a long time, but I haven't been using it's built-in events so far. Now I was trying and was stuck. Until I moved both LinqDataSource and ListView to another page, without a master page.

I do not use Update Panel. Just master page. And if I use manual methods for edit, insert, delete then it doesn't fire OnItemCommand.
