Gridview: How to add a HyperLinkField to a TemplateField in CODE?

Could you give me an example on how I'd go about dynamically creating a TemplateField with a HyperLinkField added into it...the TemplateField would then get added to a column in the GridView...? It turns out the TemplateField's ItemTemplate can only be assigned an ITemplate, and the HyperLinkField does not implement that interface. I am looking for code, not tags in the aspx page.

The DataNavigateUrlFormatString property in HyperLinkField cannot be assigned a value with ":", forexample if you wish to add "javascript:MyFunc();", and Microsoft gives the above solution as a workaround...

Appreciate it...Thanks!

Example from MSDN
<%@ Page Language="C#" AutoEventWireup="True" %>
<%@ Import Namespace="System.Data" %>

<html>

<head>

<script runat="server">

ICollection CreateDataSource()
{
DataTable dt = new DataTable();
DataRow dr;

dt.Columns.Add(new DataColumn("IntegerValue", typeof(Int32)));
dt.Columns.Add(new DataColumn("PriceValue", typeof(Double)));

for (int i = 0; i < 3; i++)
{
dr = dt.NewRow();

dr[0] = i;
dr[1] = (Double)i * 1.23;

dt.Rows.Add(dr);
}

DataView dv = new DataView(dt);
return dv;
}

void Page_Load(Object sender, EventArgs e)
{
MyDataGrid.DataSource = CreateDataSource();
MyDataGrid.DataBind();
}

</script>

</head>

<body>

<form runat="server">

<h3>HyperLinkColumn Example<h3>

<asp:DataGrid id="MyDataGrid"
BorderColor="black"
BorderWidth="1"
GridLines="Both"
AutoGenerateColumns="false"
runat="server">

<HeaderStyle BackColor="#aaaadd"/>

<Columns>

<asp:HyperLinkColumn
HeaderText="Select an Item"
DataNavigateUrlField="IntegerValue"
DataNavigateUrlFormatString="detailspage.aspx?id={0}"
DataTextField="PriceValue"
DataTextFormatString="{0:c}"
Target="_blank"/>

</Columns>

</asp:DataGrid>

</form>

</body>
</html>

detailspage.aspx
<%@ Page Language="C#" AutoEventWireup="True" %>
<html>
<head>

<script runat="server">

void Page_Load(Object sender, EventArgs e)
{
Label1.Text = "You selected item: " + Request.QueryString["id"];
}

</script>

</head>
<body>

<h3>Details page for DataGrid</h3>

<asp:Label id="Label1"
runat="server"/>

</body>
</html>



HyperLinkColumn.DataNavigateUrlField Property : Gets or sets the field from a data source to bind to the URL of the hyperlinks in the HyperLinkColumn.

HyperLinkColumn.DataNavigateUrlFormatString Property : Gets or sets the display format for the URL of the hyperlinks in the HyperLinkColumn when the URL is data-bound to a field in a data source

One more thing is that you may use Template Column. Just convert a normal column to template col. Add hyperlink in this col. Set the datavalue for this hyperlink. It's also pretty easy..

hope it would help..

I was looking for a solution (C#) that allowed me to call a jscript function with "javascript:MyFunc();" when user clicks on the HyperLink... the "for example" part may have thrown you off.

My points go to Sandip even though he doesn't provide a solution for the "javacript:" issue...

KarinLoos, I was not looking for a general way to dynamically add columns to a datagrid (specifically TemplateField with a HyperLinkField).
