.NET Forum / .NET Framework / General / August 2005comboBox_SelectedIndexChanged
I have 3 comboBoxes and the selectedIndexChanged event for all three call the same method (ShowCorrectDisplay())....basically, the UI elements change depending on which element is selected. However, the problem is that when my form initially loads, the initially selected index of only combo box is important....but my code calls the the ShowCorrectDisplay() method 3 times during initial form load even though that is unneccessary. Is there any way to do a check if (!formLoad) then ShowCorrectDisplay()? Thanks. Sorry, just correcting a sentence: However, the problem is that when my > form initially loads, the initially selected index of only ONE combo box is > important. > I have 3 comboBoxes and the selectedIndexChanged event for all three call the > same method (ShowCorrectDisplay())....basically, the UI elements change [quoted text clipped - 5 lines] > > Thanks. Here's what I do. Don't connect the selectedIndexChanged event handlers until after form load. > I have 3 comboBoxes and the selectedIndexChanged event for all three call the > same method (ShowCorrectDisplay())....basically, the UI elements change [quoted text clipped - 5 lines] > > Thanks. oh, you mean change the order of declarations?? > Here's what I do. > [quoted text clipped - 9 lines] > > > > Thanks. How do you that? > Here's what I do. > [quoted text clipped - 9 lines] > > > > Thanks. Open up the section of code entitled: #region Windows Form Designer generated code Then find the statement this.comboBox3.SelectedIndexChanged += new System.EventHandler(this.comboBox3_SelectedIndexChanged); And comment it out...// Then copy this same statement to the point in your form load, after you've populated the comboboxes. > How do you that? > [quoted text clipped - 11 lines] >>> >>>Thanks.
