Serious problem when i try to add a new record

[Adigard]

Greetings,

I have a GridTemplateColumn on my grid :

<telerik:GridTemplateColumn UniqueName="TemplateEditColumn">
    <ItemTemplate>
        <asp:HyperLink ID="EditLink" runat="server" Text="Participants"></asp:HyperLink>
    </ItemTemplate>
</telerik:GridTemplateColumn>

When i click on it,the program goes here to send the ID of the row:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{

    if (e.Item is GridDataItem)
    {

        HyperLink editLink = (HyperLink)e.Item.FindControl("EditLink");
        editLink.Attributes["href"] = "#";
        editLink.Attributes["onclick"] = String.Format("return ShowEditForm('{0}','{1}');", e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["idRDV"], e.Item.ItemIndex);

    }


}

BUT when i try to insert a new record on my grid, the program goes also here and create an ArgumentOutofRangeException

basically, it says : the index is out of range. Must be non-negative and less than the size of the collection. Parameter name: index


Can anyone help me ? thanks in advance

Hi Adigard,

You could try to add a check whether the item is in edit mode before trying to access parts of its ItemTemplate:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem && !e.Item.IsInEditMode)
    {...}
}

I hope this helps.

Kind regards,
