here, try something in this direction. I assume you want to use the RowDataBound handler as this is fired for each row as it gets bound to data. If you prefer RowCreated, the code remains the same

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
        If (e.Row.RowType = DataControlRowType.DataRow) Then
            Dim tb1 As TextBox = DirectCast(e.Row.FindControl("TextBox1"), TextBox)
            If (tb1 IsNot Nothing) Then
                tb1.Text = "something"
            End If
        End If
    End Sub

and wire the handler for RowDataBound declaratively or use the handles clause eg :

<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound"...

ouch! vb.net

Try this then :

Dim tb1 As TextBox = DirectCast(frmCheckEntry.FindControl("txtEditChkDate"), TextBox)
If tb1 IsNot Nothing Then
Page.SetFocus(tb1)
End If

in vb.net when you cast, you can use DirectCast or CType function.

I'm not able to get it to work. I can't seem to cast it to a textbox. what might i be doing wrong:

Protected Sub frmCheckEntry_ItemCreated(ByVal sender As Object, ByVal e As System.EventArgs) Handles frmCheckEntry.ItemCreated

        Dim tb1 As TextBox
        tb1 = (TextBox)(frmCheckEntry.FindControl("txtEditChkDate"))

        Page.SetFocus(tb1)

    End Sub

The page class exposes a setfocus method, use it to set the focus. NOte the code in the FormViews ItemCreated handler below eg:

<%@ Page Language="c#" %>
<%@ Import Namespace="System.Data" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            FormView1.DataSource = new string[] { "apples" };
            FormView1.DataBind();
        }
    }

<script

    protected void FormView1_ItemCreated(object sender, EventArgs e)
    {
        TextBox tb1 = (TextBox)FormView1.FindControl("TextBox1");
        if (tb1 != null)
            Page.SetFocus(tb1);
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:FormView ID="FormView1" runat="server" OnItemCreated="FormView1_ItemCreated">
    <ItemTemplate>
        <asp:TextBox ID="TextBox1" Text='<%#Container.DataItem %>'
        runat="server"></asp:TextBox>
    </ItemTemplate>
    </asp:FormView>
    </form>
</body>
</html>

Set focus on textbox w/in FormView

How do I set the focus on a textbox within a form view? I guess my real question is how do I even access a textbox within the formview?
