How to find Control in TemplateField of GridView?
208,506
Solution 1
Try this:
foreach(GridViewRow row in GridView1.Rows) {
if(row.RowType == DataControlRowType.DataRow) {
HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink;
}
}
If you are handling RowDataBound event, it's like this:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
}
}
Solution 2
You can use this code to find HyperLink in GridView. Use of e.Row.Cells[0].Controls[0] to find First position of control in GridView.
protected void AspGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
DataRowView v = (DataRowView)e.Row.DataItem;
if (e.Row.Cells.Count > 0 && e.Row.Cells[0] != null && e.Row.Cells[0].Controls.Count > 0)
{
HyperLink link = e.Row.Cells[0].Controls[0] as HyperLink;
if (link != null)
{
link.Text = "Edit";
}
}
}
}
Solution 3
I have done it accessing the controls inside the cell control. Find in all control collections.
ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls;
Label lbCod = (Label)cc[1];
