    Suspending screen updates

    Hi

    I have a winform with a panel on it. I am doing visual changes to the panel.
    Is there a way to suspend screen painting during these changes? If the whole
    form needs its display suspended then that would work for me too. How can I
    do this?

    Thanks

    Regards

      You'll get the best solution if you tell us why you want to do this. Do
      you do a lot of visual changes and do you want to speed it up? How long
      does it currently take? What kind of changes?

          Hi Armin

          I am adding several controls to the panel and would like to display them all
          at once when the update is complete.

          Many thanks for your time.

          Regards

              Can you hide the whole panel before and show it afterwards? Maybe show
              an additional "please wait..." label (or similar) during the operation.
              How long does it currently take?
              ? (just to receive an impression)

                  John,

                  Those controls where this makes sense have properties for this.

                  Have a look at the listview by instance.

                  ListView.BeginUpdate Method (System.Windows.Forms)
                  http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.beginupdate.aspx
                  Prevents the control from drawing until the EndUpdate() method is called.
