How to replace a codebehind method with an aspx method using ternary operator
- by user466663
I have an asp:hyperlink control as part of a gridview template. The code in the aspx page is given below:
asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# GetUrl(Eval("ID").ToString(), Eval("CategoryID").ToString()) %' ImageUrl="~/Images/Edit.gif"
The NavigateUrl value is obtained from the codebehind method GetUrl(string, string). The code works fine and is as follows:
protected string GetUrl(string id, string categoryID)
{
var CategoryID = string.Empty;
if (!String.IsNullOrEmpty(Request.QueryString["CatID"]))
{
CategoryID = Request.QueryString["CatID"].ToString();
}
else if (!String.IsNullOrEmpty(categoryID))
{
CategoryID = categoryID;
}
return "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + id + "&CatID=" + CategoryID;
}
I want to replace the code behind method by using a ternary operator within the aspx page. I tried something like below, but didn't work:
asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + Eval("ID") + "&CatID=" + Eval(this.Request.QueryString["CatID"].ToString()) != ""? this.Request.QueryString["CatID"] : Eval("CategoryID")) %' ImageUrl="~/Images/Edit.gif"
Any help will be greatly appreciated.
Thanks
