It’s possible to place a userpopup under columnheadercell of a datagridview?
I can not use the ShowPopup (control) method by passing headercell as a parameter because headercell is not a control. Using ShowPopup (x, y) I have the problem of how to calculate the headercell coordinates (especially if datagridview is nested in other containers).
Any suggestions?
thanks in advance
Ok
Now it works perfect.
I confirm that the problem was the single quote
Thank you very much
It’s “this” since it’s a javscript exception. The invalid token may be the single quote. Make sure it’s the correct single quote. The VB code pasted by Tiago shows the wrong single quotes (‘{0}’) since wordpress has a habit of changing the quotes.
Thank you Luca,
I’ve tried your solution but it still does not work.
I think the problem is in the eval line.
When I run it, I get an error: “invalid or unexpected token”.
Probably “this.showPopup” is incorrect because ‘this’ is CSharp syntax.
I replaced it with “me.showPopup” but it still does not work and I always return the same mistake.
Any suggestions?
Hi Angelo,
I didn’t test it but the VB version should be
Imports Wisej.Web
Public Class UserPopupEx
Inherits UserPopup
Public Overloads Sub ShowPopup(ByVal column As DataGridViewColumn)
Show()
CreateControl()
Eval(String.Format(“this.showPopup(Wisej.Core.getComponent(‘{0}’).getHeaderWidget())”, (CType(column, Wisej.Core.IWisejComponent)).Id))
End Sub
End Class
Luca,
My application is in VB. I tried your solution by converting from CSharp to VB but it does not seem to work.
I probably made some mistake in converting (I’m not very practical about Csharp). Could you give me the VB code version?
Thank you
Yes, you can add a ShowPopup method that takes in a DataGridColumn component:
public class UserPopupEx : UserPopup
{
public void ShowPopup(DataGridViewColumn column)
{
Show();
CreateControl();
Eval(String.Format("this.showPopup(Wisej.Core.getComponent('{0}').getHeaderWidget())", ((Wisej.Core.IWisejComponent)column).Id));
}
}
Short explanation of the Eval line:
“this.showPopup” invokes the showPopup method on the client which takes in a widget as a parameter.
“Wisej.Core.getComponent(‘{0}’)” retrieves the component that corresponds to the specified ID. In this case, the DataGridViewColumn component.
“.getHeaderWidget()” returns the widget for the column header, associated with the DataGridColumn component.
