Hi,
I have a gridview that at first column i bind Id and fourth colum is a temolatefield with hyperlink.

ASP.NET

<asp:TemplateField HeaderText="Description">
              <ItemTemplate>
                  <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="" Text="Download"></asp:HyperLink>
              </ItemTemplate>
          </asp:TemplateField>

I want when the gridview is loaded, Download(text of hyperlink) convert to link and its navigateUrl set to DescripPath and when i select an item from a dropdownlist GridHomework is shown but "Download" isn't converted :

C#

protected void GridHomework_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int HwId =Convert.ToInt32( e.Row.Cells[0].Text);
        Homework Hw = DB.Homeworks.Where(h => h.Id == HwId).First();
        HyperLink Hl = (HyperLink)e.Row.FindControl("HyperLink1");
        Hl.NavigateUrl = Hw.DscripPath;

    }
    GridHomework.DataBind();
}

thank you for any help.

Yes but it wasn't fired so i changed my code and gridHomework was loaded but the hyperlink column was not changed:

protected void dpdGroup_SelectedIndexChanged(object sender, EventArgs e)
{

int GroupId =Convert.ToInt32( dpdGroup.SelectedItem.Value);

CourseGroup group = DB.CourseGroups.Where(g => g.Id == GroupId).First();

IEnumerable<homework> lstHomework = group.GetHomework();

GridHomework.DataSource = lstHomework;
GridHomework.DataBind();

foreach (GridViewRow gvRow in GridHomework.Rows)
{

int HwId = (int)GridHomework.DataKeys[gvRow.RowIndex].Value;

Homework Hw = DB.Homeworks.Where(h => h.Id == HwId).First();

HyperLink link = new HyperLink();

link =(HyperLink)gvRow.FindControl("HyperLink1");

link.NavigateUrl = Hw.DscripPath;
}

GridHomework.DataBind();
}

and in html:

<asp:TemplateField HeaderText="شرح تکلیف">
<itemtemplate>
<asp:HyperLink ID="HyperLink1" runat="server">ِDownload
