View 1 RepliesI have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created.

View 2 RepliesI'm trying to create new tabs within page. When I click a link in my navmenu, it should open the Redirected page in a new tab within the page as new tab (not the browser tab). It is something like the visual studio, where we get the page opened inside a new tab when you click an item in the Solution explorer. Would any body let me know how to implement this functionality. (generate tab with close functinality). I m not talking about TabStrip.

View 4 Repliesapologies beforehand for what can possibly be a daft conceptual question. I have an ascx control that has a bunch of ASP labels and buttons in the ascx page and some other public methods and properties in the code behind. When I drop this ascx control in a page it all works fine. I now have a page with a placeholder and I am trying to dynamically create an instance of my ascx control and put it there. I then reference this control in code and while all public methods and properties are available (ie MyControl.TitleString = "Hello";MyControl.DoSomething();) none of the ASP controls are. Rather, they are all null. So MyControl.buttonSave is null, MyControl.LabelTitle is null, etc. Is this by design? Am I missing something? If not, what's the point of being able to create dynamically do this?

I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.
//Dynamically creating the Grid
protected void btnAnalyze_Click(object sender, EventArgs e)
I would like to give a TextBox in a custom WebPart the ability to AutoComplete on user entry. I am NOT allowed to use the AjaxControlLibrary OR the AjaxControlToolkit. (don't ask... that's just how it is.) Obviously, the TextBox will be instantiated within an UpdatePanel; but how would I go about the rest of this as simply as possible? I would like to be able to pull my list of items for the AutoComplete feature from three potential sources: database, web service, or collection object.
