ImageURL on c# code not showing image

Question

I have image on aspx page as:

<asp:Image ID="imgOrgLogo" runat="server" Width="50px" Height="35px" AlternateText="Image Not Found"  />

I have ready path for it in database, and I am fetching image name from database and setting up its path as:

 string path = obj.ExecuteScalar(sql);   
 imgOrgLogo.ImageUrl = "/OrgImages/" + path;
 imgOrgLogo.DataBind();

from string path I get the image name.

I checked folder OrgImages contains specified image.

But image is not viewing after running this code.

When i done inspect element from browser its showing:

   <img id="MainContent_imgOrgLogo" src="" alt="Image Not Found"

  style="height:35px;width:50px;">

Path is not getting settled.

What is wrong in my code??

Please help me.

Solution 1

Try:

<img id="MainContent_imgOrgLogo" src="" alt="Image Not Found" style="height:35px;width:50px;" runat="server" />

I added runat="server" so you can access the <img ID in codebehind and set the src.

Example: MainContent_imgOrgLogo.Src = (YOUR IMAGEPATH)

Or try (since you are talking about a ddlOrganization_SelectedIndexChanged):

if(!IsPostBack)
{
    string path = obj.ExecuteScalar(sql);   
    imgOrgLogo.ImageUrl = "/OrgImages/" + path;
    imgOrgLogo.DataBind();
}

Edit:

but on selection it should change the image.

If you want to achieve that, you should put the <img-attribute inside a UpdatePanel and on the ddlOrganization_SelectedIndexChanged-event you should paste your .ImageURL-code.

Solution 2

Change the line

imgOrgLogo.ImageUrl = "/OrgImages/" + path;

with

imgOrgLogo.ImageUrl = "~/OrgImages/" + path;

and remove

imgOrgLogo.DataBind();

well your ImageUrl attribute may be ovride by other code in your code behind.
