Good morning,
I am having a very annoying problem; my situation is that I am working on a job board website and specifically the job search page at the moment. I am returning the jobs found into a DataBound GridView (namely gvwJobs), and within the HeaderTemplate I have a DropDownList named ddlSortDirection which specifies the direction in which the sorting is performed:
<asp:ListItem Value="DESC">DOWN</asp:ListItem>
<asp:ListItem Value="ASC">UP</asp:ListItem>
As you can see, I have ensured that AutoPostBack is on. I have also created a custom event handler on the GridView's DataBound event as so:
Protected Sub gvwJobs_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvwJobs.RowDataBound
If e.Row.RowType = DataControlRowType.Header Then
ddlSortDirection.AutoPostBack = True
AddHandler ddlSortDirection.SelectedIndexChanged, AddressOf ddlSortDirection_SelectedIndexChanged
End If
End Sub
I am finding that the ddlSortDirection_SelectedIndexChanged SubProcedure is not called when the selection is changed in ddlSortDirection. I can see that a PostBack occurs, but the method is definitely not called. What I have tried doing is creating a similar DropDownList outside of the GridView and that successfully triggered the SelectedIndexChanged event without even having a custom event handler!
Please could you help me to achieve my goal of having a DropDownList firing the SelectedIndexChanged event when within a HeaderTemplate of a GridView!
Kind Regards,
Adam Sharif
