Duplicated child gridviews

[Bruno]

Hello,


When using hierarchical gridview, and acceding to the child gridview with the IDE, I noticed that at first I had only one child gridview, but after clicking on OK button, I got 2, then 4 identical gridviews. And they are displaying caption tabs saying "Table".

I tried to remove them, to keep only one, but then no child gridview was kept by the designer (gridviewTemplate was lost) , and compiling became impossible.

Is this a known bug ? Is there a way to safely remove the duplicated child gridviews and keep only one ?

Thank you for any help.

Hi again Bruno,

I haven't experienced this issue before and it sounds as though you are adding more than one child template for the same set of child data.
First of all, please have a look at this help topic on binding to hierarcical data programatically, and if you need further help, then let me know
Thanks
Richard

Here is the code I found in my Designer file :

this.MygridView.MasterGridViewTemplate.ChildGridViewTemplates.AddRange(new Telerik.WinControls.UI.GridViewTemplate[] {
            this.gridViewTemplateDetailCurrent,
            this.gridViewTemplateDetailCurrent,
            this.gridViewTemplateDetailCurrent,
            this.gridViewTemplateDetailCurrent});

when only one gridViewTemplateDetailCurrent was needed. This code was obviously added by the IDE (not by me).

Removing by hand 3 gridViewTemplateDetailCurrent of this list solved my problem.
