Say I have an UltraExplorarBar on the left in the MainForm. On the bar there's 3 items, customer A, B, and C, and the MainForm acts as MDI Parent. In the project I have a CustomerForm so that if you click on the item on the bar, a customer form pops up on the right in MainForm. The problem is, how can I ensure that there's only one CustomerForm pops up for customer A, if user clicks the customer A icon serveral times? It looks like that I can't use singleton pattern on the CustomerForm becuase serveral customers share the same form object.
What whould be the best way to implement the? Is there any build-in thing in Infragistics that can help with this?
Use this method ..may be usefull for u ...i created based on form text ...replace with form name (MdiChildren[i].name) ...like that..
if (ActivateThisChild(formText) == false) then open form logic ...
---------------------------------------------------------------------------------
{
Boolean formSetToMdi = false;
// loop for all the mdi children
// find the Mdi child with the same name as your form
// if found just activate it
}
// if the given form not found as mdi child return false.
else
We don't provide any easier way to do what you are after. If you are using VB, the singleton form pattern is built in. In C#, you can enumerate the forms and MdiChildren collection and check to see if the form is loaded before you create a new instance of it.
Let me know if this helps or if I misunderstood what you are after,
Thanks
