ASP.NET UpdatePanel Lock All TextBox Controls After Post-back?

Nov 2, 2010

My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.

why it locked all TextBox controls after the post-back?

Here's why I use UpdatePanel:

During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.

here's the mark-up of the ASP.NET page: [URL]

Show New Form And Lock Other One?

Jul 24, 2009

I have my main form then a progress bar form that is shown when the program is running. I simply want to keep the progress bar form on top of the other form and make the other form so it can't be changed.

I've tried form2.showdialog, but that stops the code in the main form from running so it's no good.

form2.show(me) just keeps form2 ontop of form1

me.topmost in form2 does the same as the last thing

setting the form1.enabled = false isn't something I want to do since you can't even move the form when it's like that

So really I'm at a complete loss here

also how can I get the progress to start in the center of form1? There is a setting in the form properties but is doesn't seem to work.

I have a Dialog which I'm calling via Loading.Show()Can I lock the position and location to the parent form? In such a way so if the parent is minimised or moved, the child will stay centred to the parent?

I was using ShowDialog() but this obviously stops the parent from being accessible. This is being used to display a progress gif. (Child is 50% opacity)

Controls Not Return All The Child Controls For The Form?

Apr 15, 2010

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

Raise Keyboard Events To Windows From Form Application

Jun 21, 2012

Ok, so I'm writing a basic windows form application in VB.net as you do and need to be able to raise keyboard events based on data received from the serial port. I'm able to receive the characters that I want (lets say a lower case c) and display them. Its also easy enough for me to find the keycode. What I want to do though is tell windows that key "c" has been pressed. The application is paired to a bluetooth terminal, I wanted to have the experience of writing the code behind this myself rather than using another library although it seems I've failed already. How would I go about doing this?
