Problem adding control using AddAt method [ASP.NET]
On my page I have the following Image control.
<asp:Image ID="Image1" ImageUrl="~/images/icons/returnarrow.gif" runat="server" />
Then on Page_Load I am doing the following.
Image1.Controls.AddAt(1, new LiteralControl("ChildControl2"));
So what this should do (theoretically) is add a new LiteralControl next to the image. But it doesn't. However, If I change the index to 0 and the Image to a GridView con开发者_开发技巧trol it works.
What am I doing wrong?
Don't modify the Controls collection. Use a PlaceHolder instead.
I don't think so Image1.Controls.AddAt
will add any control next to Image control because Image1.Controls
is a collection of child controls of Image1
, may be this.Controls.AddAt
will work
You should be trying to embed another control in an image. Use a PlaceHolder as the parent container, and add the Image and Literal to the PlaceHolder.
