Can I programmatically add a linkbutton to gridview?
- by pschorf
I've been looking through some similar questions without any luck. What I'd like to do is have a gridview which for certain items shows a linkbutton and for other items shows a hyperlink. This is the code I currently have:
public void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var data = (FileDirectoryInfo)e.Row.DataItem;
var img = new System.Web.UI.HtmlControls.HtmlImage();
if (data.Length == null)
{
img.Src = "/images/folder.jpg";
var lnk = new LinkButton();
lnk.ID = "lnkFolder";
lnk.Text = data.Name;
lnk.Command += new CommandEventHandler(changeFolder_OnCommand);
lnk.CommandArgument = data.Name;
e.Row.Cells[0].Controls.Add(lnk);
}
else
{
var lnk = new HyperLink();
lnk.Text = data.Name;
lnk.Target = "_blank";
lnk.NavigateUrl = getLink(data.Name);
e.Row.Cells[0].Controls.Add(lnk);
img.Src = "/images/file.jpg";
}
e.Row.Cells[0].Controls.AddAt(0, img);
}
}
where the first cell is a TemplateField. Currently, everything displays correctly, but the linkbuttons don't raise the Command event handler, and all of the controls disappear on postback.
Any ideas?
