View 6 RepliesBackground: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.

I am working on an ASP.NET web application using .net 4.0 and VS2010.
I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.
The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.
The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.
If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.
I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.
Here is my code: (I removed creating the Textboxes because that is not part of the problem.

I have a fileupload Control and I made this as invisible. I want to fire browse button of that fileupload control when I clicked a nother button.How can I do?
View 1 RepliesI have a form with several submit buttons. I would like the button's click events to fire when enter is pressed based on which textboxes currently have focus. I am able to specify one button using the code below by adding the onkeydown event to the body of the page and checking for Enter's keyCode
<body onkeydown="if(event.keyCode==13){document.getElementById('btnSearch').click();}">
</body>
I assume this code can be modified or call a function to perform a conditional to see if txtSearch or txtSubmit has focus and specify btnSearch or btnSubmit accordingly, but I am not experienced with javascript.
I want to call Textbox.OnTextChange event without having to click a submit button or any button. How can I do this? As I enter text in the textbox, I want the ontextchange event to fire.

Code:
WithEvents btnAddToCart as Button
Private Sub BuildCart()

I'm actually loading a productID into the "ToolTip" property of the button. In the click event of the btnAddToCart, the code is not being executed when I set a breakpoint.
I have a web page that contains a couple of button controls. The page is pretty simple, just trying to add a record to the DB. When I click the Submit button, every function/procedure that is supposed to be executed does execute except the Button Click Event. I've checked to make sure all occurrencs of the control are named correctly in the code-behind as well as the javascript. I've set the debugger to debug every function/procedure as well and nothing happens. Why this would occur.
