IExplorer 11 Null Reference Error in Radconfirm

[Jens]

Hello,

I am open Radconrim within onclick event in Coede Behind. Only in Iexplorer (Version 11) I get Null Reference error in set-animation.

Here the code:

ASP Page:

<telerik:RadButton ID="ImgBtnDelete" runat="server" Width="120px" Text="Delete" OnClick="ImgBtnDelete_Click">
                    <Icon PrimaryIconCssClass="iconDelete" PrimaryIconLeft="4" PrimaryIconTop="4" />
</telerik:RadButton>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true"
        VisibleStatusbar="False" Behavior="None" BorderStyle="None" KeepInScreenBounds="True">
</telerik:RadWindowManager>

function confirmCallBack_Delete(arg) {
                if (arg) {
                    var ajaxManager = $find("<%= RadAjaxManagerDataCheckDetail.ClientID %>");
                    ajaxManager.ajaxRequest("confirmCallBack_Delete");
                    closeWindow();
                }
}

<telerik:RadAjaxManager ID="RadAjaxManagerDataCheckDetail" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1" OnAjaxRequest="RadAjaxManagerDataCheckDetail_OnAjaxRequest">
        <AjaxSettings>

<telerik:AjaxSetting AjaxControlID="ImgBtnDelete">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="ImgBtnDelete" />
                </UpdatedControls>
            </telerik:AjaxSetting>

</AjaxSettings>
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" BackgroundPosition="Center"></telerik:RadAjaxLoadingPanel>

 

Code Behind:

protected void ImgBtnDelete_Click(object sender, EventArgs e)
        {
            RadWindowManagerDataCheckDetail.RadConfirm("Are you sure to Delete the DataCheck?", "confirmCallBack_Delete", 330, 100, null, "Are you sure?");
        }

protected void RadAjaxManagerDataCheckDetail_OnAjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            if (e.Argument == "confirmCallBack_Delete")
            {
                DeleteDataCheck();
            }

        }

Hi Jens,

I tested the provided configuration but no errors are thrown at my end. Can you, please, make sure that IE11 is not running in compatibility mode. I am asking you that as this mode is not supported and may lead to such errors.

If this is not the case, please, try my test page (attached to this reply) and see if you are facing the same problem with.

Are you facing the same issue with your own project or with the page attached in my previous reply? If the latter is true, can you, please share some more details on the matter? Can you confirm that you are using the latest version of the control like stated in the ticket info (2017.3.913)?
