My code is :

protected System.Web.UI.HtmlControls.HtmlGenericControl frame1;protected void Page_Load(object sender, EventArgs e)

{

string selectedLanguage = Convert.ToString(Session["selectedLanguage"]);

UICulture = selectedLanguage;

Culture = selectedLanguage;

Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(selectedLanguage);

Thread.CurrentThread.CurrentUICulture = new CultureInfo(selectedLanguage);

string strResourcesPath = Server.MapPath("App_LocalResources");

ResourceManager rm = ResourceManager.CreateFileBasedResourceManager("resource", strResourcesPath, null);

HtmlControl frame1 = (HtmlControl)this.FindControl("region1");frame1.Attributes["src"] = rm.GetString("022").ToString();

}

And iframe is:

</div>

Sandya81:
HtmlControl frame1 = (HtmlControl)this.FindControl("region1");

Sandya81:
<iframe id="region1" name = "region1" src="regions/Russia.htm" frameborder="0" width="220" scrolling="auto" height="280" runat="server"></iframe>

Hi Sandya81,

Please change above two lines to below two lines to solve your problem:

HtmlContainerControl frame1 = (HtmlContainerControl)this.FindControl("region1");

<iframe id="region1" id= "region1" name = "region1" src="regions/Russia.htm" frameborder="0" width="220" scrolling="auto" height="280" runat="server"></iframe>

Hope it helps,

Hong Gang
