Hello Christian,

I'm not clear as to where you have placed your grid. But if you want to access the grid when you kow its ID then you can use the FindControl method:

C#:

protected void Page_Load(object sender, EventArgs e)
    {
        RadGrid grid = (RadGrid)Page.FindControl("RadGridID");
    }

Thanks

Hi Christian,

The above given code will work fine if you have placed the Grid in a page with its ID as RadGrid1. Check whether you have placed the Grid normally in a page or in a usercontrol and also check whether you are accessing the Grid using its correct ID. If this does not help consider sending the entire aspx code.

Thanks

We use the RadGrid in a Usercontrol:

<   asp:HiddenField ID="ViewState_RG0" runat="server" Value="" />       <div id="D_0" runat="server" class="" style="width: 110px; margin-top: 2px; overflow: hidden;

display: inline; text-align: right">

<rc:HeaderContainer ID="D_01" runat="server" HeaderText=" " Width="100%" ControlsDir="~/rcControls/HeaderContainer">

<asp:PlaceHolder ID="PlaceHolder0" runat="server" />

</rc:HeaderContainer>

</div>

The RadGrid itsself is created with codr behind:

Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
    CreateGrid()
End Sub

Private Sub CreateGrid(ByVal Index As Integer)
dim g as RadGrid
' build RadGrid
' do something amazing

    Me.PlaceHolder0.Controls.Add(g)
    Me.ViewState_RG0.Value = g.ClientID
        RadGrid0_ClientID = g.ClientID
End Sub

Public Property RadGrid0_ClientID() As String
        Get
            Return CStr(Me.ViewState("RadGrid0_ClientID"))
        End Get
        Set(ByVal value As String)
            Me.ViewState("RadGrid0_ClientID") = value
        End Set
End Property

It doesn't work with:

g = new RadGrid();
g = DirectCast(FindControl(RadGrid0_ClientID), com.regiocom.Web.UI.WebControls.TelerikGrid)
g = DirectCast(FindControl(Me.ViewState_RG0.Value), com.regiocom.Web.UI.WebControls.TelerikGrid)

Anny Idea?

Thanks

Hi Christian,

Since the RadGrid is inside the UserControl try accessing the Grid from the UserControl as shown below.

VB:

//try accessing the webusercontrol using the correct ID

Dim Grid As RadGrid = DirectCast(WebUserControl1.FindControl("RadGrid1"), RadGrid)

Thanks
