How to Set Focus on a Control in ASP.NET using VB.NET
  • 5779

In ASP.NET 4.0, you can use two methods to set focus on controls.

First, by using the control's Focus method. Second, calling page's SetFocus method and passing ID of the control in this SetFocus method.

The following code snippet sets focus on TextBox1 by calling its Focus method on Page load event.

 

Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As System.EventArgs)
TextBox1.Focus()
End Sub 

The following code snippet sets focus on a TextBox control with ID TextBox1.

Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs)
        SetFocus(TextBox1)
End Sub

You can also set the default focus on a control by using the defaultfocus tag of a Form.

The following code snippet sets default focus on TextBox1.

<form id="form1" runat="server" defaultfocus="TextBox1" >
    <div>
      <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
      <br />
      <asp:Button ID="Button1" runat="server" Text="Button" />
      <br />
    </div>
  </form>
