How to set focus in a GridView

[ad]

I used ASP.NET 2.0.
When I edit a row in a GridView.
How can I set the focus to the first editable column?

You might want to handle the OnRowDataBound event from the GridView:

protected void _grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow && (e.Row.RowState
& DataControlRowState.Edit) != 0)
{
Control c = e.Row.Cells[2].Controls[0];
this.SetFocus(c);
}
}

The trick is to know which column in e.Row.Cells and then which control in
that Cell's Controls collectiono to set focus on.

You cound also try

Public Shared Sub SetFocus(ByVal control As Control)
If control.Page Is Nothing Then
Throw New ArgumentException("The Control must be added to a Page
before you can set the IntialFocus to it.")
End If
'If the control is enabled and visible select it
If control.Visible And control.EnableViewState Then
If control.Page.Request.Browser.JavaScript = True Then
' Create JavaScript
Dim s As StringBuilder = New StringBuilder
s.Append(vbCrLf + "<SCRIPT LANGUAGE='JavaScript'>" + vbCrLf)
s.Append("<!--" + vbCrLf)
s.Append("function SetInitialFocus()" + vbCrLf)
s.Append("{" + vbCrLf)
s.Append(" try " & vbCrLf)
s.Append(" {" & vbCrLf)
s.Append(" document.")
' Find the Form
Dim p As control = control.Parent
While Not (TypeOf p Is System.Web.UI.HtmlControls.HtmlForm)
p = p.Parent
End While
s.Append(p.ClientID)
s.Append("['")
s.Append(control.UniqueID)
' Set Focus on the selected item of a RadioButtonList
If TypeOf control Is RadioButtonList Then
Dim rbl As RadioButtonList = control
If Not rbl Is Nothing Then
Dim suffix As String = "_0"
Dim t As Int32 = 0
Dim li As ListItem
For Each li In rbl.Items
If li.Selected Then
suffix = "_" + t.ToString()
Exit For
End If
t = t + 1
Next
s.Append(suffix)
End If
End If
' Set Focus on the first item of a CheckBoxList
If TypeOf control Is CheckBoxList Then
s.Append("_0")
End If
s.Append("'].focus();" + vbCrLf)
s.Append(" }catch(e){}" & vbCrLf) ' close the try, catch
block
s.Append("}" + vbCrLf)
If control.Page.SmartNavigation Then
s.Append("window.setTimeout(SetInitialFocus, 500);" +
vbCrLf)
Else
s.Append("window.onload = SetInitialFocus;" + vbCrLf)
End If
s.Append("// -->" + vbCrLf)
s.Append("</SCRIPT>" + vbCrLf)
' Register Client Script
control.Page.RegisterClientScriptBlock("InitialFocus",
s.ToString())
End If
End If
End Sub
