First image not showing

[Carlos]

Hello I have the below code:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ImageSlider2.ascx.cs" Inherits="UserControls_ImageSlider2" %>

<asp:Panel id="ImageGalleryPnl" Visible="false" runat="server">
<telerik:RadImageGallery ID="RadImageGallery1" Width="350px" DisplayAreaMode="Image" LoopItems="true" runat="server" >
<ImageAreaSettings Height="250px" ShowDescriptionBox="false" />
<ThumbnailsAreaSettings Mode="ImageSlider" />
<ClientSettings AllowKeyboardNavigation="true">
</ClientSettings>
</telerik:RadImageGallery>

</asp:Panel>
<asp:Panel ID="MsgPnl" Visible="true" runat="server">
<asp:Label ID="lblMessage" Text="No images avaliable at this time" runat="server"></asp:Label>
</asp:Panel>

The imageGallery is in a ajax ModalPopupExtender. It is populated dynamically just before showing the popup as below:

Method: Grid_OnRowCommand:
rowIndex = Integer.Parse(e.CommandArgument) Mod grdLocations.PageSize
oRow = grdLocations.Rows(rowIndex)
grdLocations.SelectedIndex = rowIndex

Dim lblAddress As Label = oRow.FindControl("lblAddress1")
Dim lblCityState As Label = oRow.FindControl("lblCity")

Dim lblLocDescription As Label = oRow.FindControl("lblLocDescription")
lblModalInfo.Text = lblLocDescription.Text
sFullAddress = lblAddress.Text & " " & lblCityState.Text
lblModalFooter.Text = sFullAddress

ImageSlider1.showSlider(True)

ImgContent.Visible = False
Dim lblLocation As Label = oRow.FindControl("lblLocation")

ImageSlider1.sMSClient = _sMSClient
ImageSlider1.sLocation = lblLocation.Text
ImageSlider1.populateGallery()
ModalPopupExt1.Show()

The imageGallery works ok, I can navigate through all the images, but the first one is always showing in black after displaying the popup. If I move to next image and then back to the first I can see it. So it is loaded. It looks like it were inactivated or something.

Please advice.

Hi Carlos,

The behavior you describe seems rather strange. Would you try to upgrade the controls to the latest version and see how it works? The current release of the controls is 2014.3.1209.
