Changing from asp Button to RadButton generate javascript errors within a RadGrid

[Gary Meagher]

In the following code, if I change Button to RadButton I'm getting all sorts of javascript exceptions from Telerik internal code.

private void CreateLinks(GridItemEventArgs e, SubsEntity type)
    {
        if (e.Item is GridDataItem && e.Item.ItemIndex != -1)
        {
            Button editLink = (Button)e.Item.FindControl("btnEdit");
            //editLink.PostBackUrl = "ManageSubscriptions.aspx?EditMode=true&Type=" + type + "&SubscriptionID=" + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["SubscriptionID"];
            editLink.PostBackUrl = UIMgr.GetEditSubscriptionURL(this.DataSet, type, e.Item.ItemIndex);
            Button removeLink = (Button)e.Item.FindControl("btnRemove");
            removeLink.Attributes["href"] = "#";
            removeLink.Attributes["onclick"] = String.Format("return ShowConfirmForm('{0}','{1}');", e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["SubscriptionID"], e.Item.ItemIndex);
        }
    }
    #endregion

    protected void gridProductSubs_ItemCreated(object sender, GridItemEventArgs e)
    {
        CreateLinks(e, SubsEntity.ResearchProduct);
    }

<telerik:GridTemplateColumn UniqueName="Remove">
                    <ItemTemplate>
                        <asp:Button ID="btnRemove" runat="server" CausesValidation="False"
                            ToolTip="Remove" Text="Remove" />
                    </ItemTemplate>
                    <HeaderStyle Width="35px" />

Hello Gary,

I think the problem is caused by the fact that you set the "onclick" and "href" attributes of the RadButton control. You should use the OnClientClicked property (clicked client-side event) for this purpose.
Could you please provide the ShowConfirmForm JavaScript function? Once I know the code executed when the button is clicked, I can suggest how to change your code so that the problems are avoided.

Sincerely yours,
Pero
