how to :hyperlinkcolumn in string array

[edelwater]

Simple question:

i define an array :

subdir = System.IO.Directory.GetDirectories("\\bla\\");
        string CorrectString;
        testGrid1.DataSource = subdir;
        testGrid1.DataBind();

i define a datagrid :

<asp:datagrid id="testGrid1" runat="server" AutoGenerateColumns="False" EnableViewState="False">
                                <Columns>
                                    <asp:HyperLinkColumn HeaderText="Test" DataNavigateUrlField="subdir" DataNavigateUrlFormatString="relreq.aspx?id={0}"/>
                                </Columns>
                            </asp:datagrid>

Why does it give me the error :

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Web.HttpException: A field or property with the name 'subdir' was not found on the selected datasource.

edelwater,
the best way to handle this case as create a datatable and populate it from your array
the following code should work for you

private void Page_Load(object sender, System.EventArgs e)
{
string [] subdir = System.IO.Directory.GetDirectories(Server.MapPath("/TestCsharp/"));
	DataTable dt=new DataTable();
	DataRow dr;
	dt.Columns.Add(new DataColumn("Directory",typeof(string)));

foreach (string str in subdir)
{
			
       dr=dt.NewRow();
       dr[0]=str;
       dt.Rows.Add(dr);
}
testgrid1.DataSource =new DataView(dt);
testgrid1.DataBind();
}

HTML Code should be like

<asp:datagrid id="testgrid1" runat="server" autoGenerateColumns="False">
<Columns>
<asp:HyperLinkColumn DataNavigateUrlField="Directory" DataNavigateUrlFormatString="relreq.aspx?id={0}"DataTextField="Directory" HeaderText="Directory"></asp:HyperLinkColumn>
</Columns>
</asp:datagrid>

Hope that helps
Good luck
