Displaying wait cursor in while backgroundworker is running
- by arc1880
During the start of my windows application, I have to make a call to a web service to retrieve some default data to load onto my application. During the load of the form, I run a backgroundworker to retrieve this data. I want to display the wait cursor until this data is retrieved. How would I do this?
I've tried setting the wait cursor before calling the backgroundworker to run. When I report a progress of 100 then I set it back to the default cursor. The wait cursor comes up but when I move the mouse it disappears.
Environment:
Windows 7 Pro 64-bit
VS2010 C# .NET 4.0
Windows Forms
EDIT:
I am setting the cursor the way Jay Riggs suggested. It only works if I don't move the mouse.
**UPDATE:
I have created a button click which does the following: When I do the button click and move my mouse, the wait cursor appears regardless if I move my mouse or not.
void BtnClick()
{
Cursor = Cursors.WaitCursor;
Thread.Sleep(8000);
Cursor = Cursors.Default;
}
If I do the following: I see the wait cursor and when I move the mouse it disappears inside the form. If I move to my status bar or the menu bar the wait cursor appears.
Cursor = Cursors.WaitCursor;
if (!backgroundWorker.IsBusy)
{
backGroundWorker.RunWorkerAsync();
}
void backGroundWorkerDoWork(object sender, DoWorkEventArgs e)
{
Thread.Sleep(8000);
}
void backGroundWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
Cursor = Cursors.Default;
}
If I do the following: The wait cursor appears and when I move the mouse it still appears but will sometimes flicker off and on when moving in text fields.
if (!backgroundWorker.IsBusy)
{
backGroundWorker.RunWorkerAsync();
}
void backGroundWorkerDoWork(object sender, DoWorkEventArgs e)
{
UseWaitCursor = true;
Thread.Sleep(8000);
}
void backGroundWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
UseWaitCursor = false;
}
