I wanted to make this functionality in composite control
here is button class
[code]....
Situation:
1) Click on 'Check' button and the button will disable
2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).
Here are 2 code situations (1):
[Code]....
and if I do this way (2),:
[Code]....
it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.
how to disable the button and run processing code during the click event and be able to navigate to a new page?

I have two buttons on my web form. When clicking on the first button, the event does not fire. Here's what I've placed in the click event handler:
protected void btnRFC_Click(object sender, EventArgs e)
{
string strDOB = drpDay.SelectedValue + "/" + drpmonth.SelectedValue + "/" + txtyear.Text;
string strRFC = CURPRFC.CalcularRFC(txtfirstname.Text, txtmiddlename.Text, txtlastname.Text, strDOB );
txtrfc.Text = strRFC;
}
strDOB is needed to get the date fields into one string used in CalcularRFC for the date value. The event handler for the second button is too large to post, but currently works as expected. But, the above handler does not return a value to txtrfc. Can someone point me in the right direction?

The problem is, when i type something in Departmetn textbox, and click on the button, you have to click twice to get the actual results up. This is because the first click is doing the "AutoPostBack" part from the text box, and then you have to click again to make the actual click postback to happen.

How do I write code for an asp:button in vb that will scroll to a textbox on the html page when clicked?
View 1 RepliesI have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?

I'm trying to let a user enter the name of a website in a textbox and click on a button. When the button has been clicked the website URL should be sent to a method which will use a WebBrowser to navigate to the website and take a screenshot of it. Further it should afterwards grab this screenshot and generate a thumbnail of it.
... And the tricky part
The tricky thing is that according to MSDN the System.Drawing should not be used in neither Windows or ASP.NET services, which leaves me with 2 approaches:
Ignore the MSDN and implement the class which contains the necessary methods.
Create a WCF Service with the necessary methods.
