Try dataGridView1.ClearSelection(); after populating the grid with data. That should de-select anything that is selected.

DatagridView1.Rows(0).Selected = False

When you refresh, you do the postback again, thus the button press will occur again.

This happens because you are refreshing the last operation - which was the javascript doPostback operation. If you don't want this to happen, I would suggest that you change the architecture so you don't need the postback to happen.

Can you Help me in changing the Architecture

Well, you may want to look into Ajax. This doesn't use postbacks.

There is such option available. U mean to say Ispostback Option. If i give the Ispostback option. When the page refresh that will also run.

Hi,
Im trying to print a data grid view. I currently have 2 methods, one converts the control to an image (DrawToBitmap) and the other goes through the data rows and draws strings.
The problem i'm having is when converting the control to a bitmap, since it only displays what is on the screen, and not the whole control.
Bitmap dataGridViewImage = new Bitmap(dataGridView.Width, dataGridView.Height);<br />
Rectangle dataGridRects = new Rectangle(0, 0, dataGridView.Width, dataGridView.Height);<br />
dataGridView.DrawToBitmap(dataGridViewImage, dataGridRects);
The above code is what i do to convert it to an image. I played around with it abit, and found that if i changed the dataGridView.Width/Height values, it would actually display whats not on the screen. However, since i never know how big the
dataGridView is, how would get the correct size?
Any ideas/anyone had this before?
Regards,
Gareth.

Hi,
Have a Scenario like below .
In my prog. there's Async. calls to listen messages from network. Whenever any error occurs i have to pop-up a message window to user. I used Raise event whenever i got error. Raise event calls a Notification manager delegate which will create the notification form and pop up. initially this window greyed out. But added DoEvents()soon after creating window solved the problem.Now i'm able to click on the cancel button in the window. That is control is not transferred to notification window. where as i can still work with other opened windows.
How do i pass control focus to notifaction message box.

Hello everbody!
Just looked threw my project and found code which I don't like at all.
I'm having an instance of DataRow and go threw it in a loop.
There I need to store the data for example in a double array.
This is what I do now:
if (myrow[x].GetType() == typeof(System.Double))
{
doublearray[x]= (double)myrow[x];
}
For reference types I would use the "as" operator!
Is there a nicer way to do this?
Thanks for suggestions!
All the best,
Martin

if (myrow[x] is System.Double)
(I rarely use as; I usually just cast.)

Hello,
PIEBALDconsult wrote: if (myrow[x] is System.Double)
Does this compile?
I thought it's (is and as) only working for reference type.
All the best,
Martin

It's better to try something even if you think it won't work.
