Dynamically Set Header Text Changes on Sort

[Brad]

I am currently dynamically changing the Header Text of one of my grids using the following code:

Protected Sub gvYearByYearValueProjection_DataBound(sender As Object, e As System.EventArgs) Handles gvYearByYearValueProjection.DataBound
        Dim Season As Integer = Utility.GetCurrentSeason
        Dim headerItem As GridHeaderItem = gvYearByYearValueProjection.MasterTableView.GetItems(GridItemType.Header)(0)
        headerItem("Yr1").Text = Convert.ToString(Season & "-" & Right(Season, 2) + 1)
        headerItem("Yr2").Text = Convert.ToString(Season + 1 & "-" & Right(Season, 2) + 2)
        headerItem("Yr3").Text = Convert.ToString(Season + 2 & "-" & Right(Season, 2) + 3)
        headerItem("Yr4").Text = Convert.ToString(Season + 3 & "-" & Right(Season, 2) + 4)
        headerItem("Yr5").Text = Convert.ToString(Season + 4 & "-" & Right(Season, 2) + 5)
        headerItem("Yr6").Text = Convert.ToString(Season + 5 & "-" & Right(Season, 2) + 6)
    End Sub

I have also used this code as well but get the same result:

Protected Sub gvYearByYearValueProjection_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles gvYearByYearValueProjection.ItemDataBound
    Dim Season As Integer = Utility.GetCurrentSeason
    If TypeOf e.Item Is GridHeaderItem Then
        Dim header As GridHeaderItem = DirectCast(e.Item, GridHeaderItem)
        header("Yr1").Text = Convert.ToString(Season & "-" & Right(Season, 2) + 1)
        header("Yr2").Text = Convert.ToString(Season + 1 & "-" & Right(Season, 2) + 2)
        header("Yr3").Text = Convert.ToString(Season + 2 & "-" & Right(Season, 2) + 3)
        header("Yr4").Text = Convert.ToString(Season + 3 & "-" & Right(Season, 2) + 4)
        header("Yr5").Text = Convert.ToString(Season + 4 & "-" & Right(Season, 2) + 5)
        header("Yr6").Text = Convert.ToString(Season + 5 & "-" & Right(Season, 2) + 6)
    End If
    If TypeOf e.Item Is GridDataItem Then
        Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)
    End If
End Sub

The problem I am running into is when I sort another grid on my page the headers resort back to Yr1, Yr2, Yr3, etc....

I am not sure where my error is, but I would be thrilled with any assistance.

Thanks,

Brad

Hello Brad,

Try setting the Header Text in PreRender event.
VB:

Protected Sub gvYearByYearValueProjection_PreRender(sender As Object, e As EventArgs)
    RadGrid1.MasterTableView.GetColumn("UniqueName").HeaderText = "HeaderText"
    RadGrid1.MasterTableView.Rebind()
End Sub
