Hi friends,

I need to display image from back-end code.

Here my code:
Events.aspx.cs:

C#

switch (sExtension)
{
    case "docx":
        SLogo = "../assets/images/Events/word_logo.jpg";
        break;
    case "doc":
        SLogo = "../assets/images/Events/word_logo.jpg";
        break;
    case "ppt":
        SLogo = "../assets/images/Events/ppt_logo";
        break;
    case "jpg":
        SLogo = "../assets/images/Events/jpg_logo";
        break;
    case "pdf":
        SLogo = "../assets/images/Events/pdf_logo";
        break;
}

Events.aspx

XML

<img id="logo_img" src="" alt="" />

But in Evets.aspx.cs, I can't access this image control.

I need to access this as, logo_img.src = sLogo;

Solution 1

Use Asp.Net Image[^] Control.

XML

<asp:Image ID="logo_img" runat="server" AlternateText="SomeAlternateTextForImage"></asp:Image>

Now do like below in aspx.cs page.

C#

logo_img.ImageUrl = sLogo;

No in backend,the id name is not accepting. that is if i type logo_img,it doesn't show its properties

It is very strange. Have you added the Image control on aspx page as I said?

yes.. I added img control as you said. but it doesn't add in Events.aspx.designer.cs file.

Then delete this control. Now add one Image control from the ToolBox. Then build the project.

After that try to access it from code behind.
