Parser Error in IFrame When added in Application Page

Question

0.00/5 (No votes)

I am creating a SharePoint-2013 web-part in that I have created Application Page.

In that page I am using <iframe> element. But it is giving me error like:

XML

Parser Error
-------------------------------------------------------------------------------------
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: The base class includes the field 'frame1', but its type (System.Web.UI.HtmlControls.HtmlIframe) is not compatible with the type of control (System.Web.UI.HtmlControls.HtmlGenericControl).

Source Error:


Line 362:                <tr>
Line 363:                    <td>
Line 364:                        <iframe id="frame1" frameborder="0"  runat="server" scrolling="no" width="100%" height="200px" style="margin: 0px; padding: 0px;" visible="false"></iframe>
Line 365:                    </td>
Line 366:                </tr>


Source File: /_layouts/15/OpportunityViewWP/Dashboard.aspx    Line: 364

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.17929

But when I am adding the same <iframe> in Visual-Web-Part it works properly.

Code Which I have used:

XML

<tr>
    <td>
        <iframe id="frame1" frameborder="0"  runat="server" scrolling="no"
               width="100%" height="200px" style="margin: 0px; padding: 0px;"
               visible="false"></iframe>
    </td>
</tr>

What is the reason behind this? Can anyone help me to solve this problem.?

Thanks in advance.!!

Hey I need the complete page code to analyse not just where the parse error is coming as the application pages wont support the controls in some parts of the layout

Hey, This is the only thing that I am using in this page. The other code is nothing but the SharePoint's necessary import and register statements.... nothing else....

it solved using code behind c# in your web part or your Application page as follow

public partial class VisualWebPart1UserControl : UserControl
{
protected void Page_Load(object sender, EventArgs e)
{

string url = "" ;

string output;
output = "

";

this.Controls.Add(new LiteralControl(output));
}
