Hello

I have a complex grid with a GridButtonColumn where I want to set some parameters in codebehind. I'm using RadGrid1_PreRender for this.

Strangely, it only works after I used the pager to change page and not on first load... 

What am I missing here? I also Page_Load, Page_PreRender, OnColumnCreated, still it just never works on first load and it's driving me insane :/

Thanks!!

protected void GridMaster_PreRender(object sender, EventArgs e)
        {         
                foreach (GridColumn col in GridMaster.MasterTableView.Columns)
                {
                    if (col.UniqueName == "DeleteEntryCommand")
                    {
                        var deleteColum = col as GridButtonColumn;
                        // deleteColum.ConfirmText = RessourceHelper.GetRessource(name: "KontraktLoeschenBestaetigen", kurzText: false, textIfEmpty: "Soll der Kontrakt wirklich gelöscht werden?", languageId: null);
                        deleteColum.ConfirmTitle = RessourceHelper.GetRessource(name: "KontraktLoeschenBestaetigenTitel", kurzText: false, textIfEmpty: "Kontrakt löschen", languageId: null);
                        deleteColum.ConfirmTextFormatString = RessourceHelper.GetRessource(name: "KontraktLoeschenBestaetigen", kurzText: false, textIfEmpty: "Soll der Kontrakt {0} wirklich gelöscht werden?", languageId: null);
                        deleteColum.ConfirmTextFields = new string[] { "Referenz" };
                    }
                }
        }

 

<telerik:GridButtonColumn
 UniqueName="DeleteEntryCommand"
 CommandName="Delete"
 ConfirmDialogType="RadWindow"
 ConfirmDialogWidth="300"
 ConfirmDialogHeight="150"
 Text=""
 ItemStyle-HorizontalAlign="Center"
 ItemStyle-CssClass="radGridDeleteColumn"
 ButtonCssClass="fa fa-trash-o fa-1x radGridDeleteButton">
 <HeaderStyle Width="40" />
</telerik:GridButtonColumn>

Hello,

I tested the behavior and it is working as expected on my end when the GridButtonColumn settings are changed in the Page_Load event. I am attaching a sample project I used for testing. Give it a try and see how it works for you.

Hello Viktor

Thank you for your answer. But I was assigned to another project for the last weeks and couldn't look in to the issue. Now the link you provided is dead.

Is it possible to provide it again? (Sorry about that...)

I looked into issue again, now on another project with GridButtonColumn but this time in DetailTables. Same effect: button values change after first postback, but not on first page load... There must be some thing I to fundamentally wrong....
