Question

I have a problem. Currently, I set the textbox value during PageLoad. However, this triggers the textbox change event.

Markup

    <asp:TextBox ID="txtToDate" CssClass="text" 
runat="server" Width="100px" ReadOnly="false" 
AutoPostBack="true" ></asp:TextBox>

On pageload

txtToDate.Text = Format(Now.Date, "MM/dd/yyyy")

Textchange Event

    Protected Sub txtToDate_TextChanged(ByVal sender As Object, 
ByVal e As System.EventArgs) Handles txtToDate.TextChanged
        Me.Grid.Visible = False
    End Sub

How can I prevent the change during PageLoad from triggering the texbox change event?

Answer 1

As mentioned in your question, you don’t want to hide the grid during the PageLoad event, but you want to hide the Grid on the TextChange event of the Textbox. You can try something like…

Protected Sub txtToDate_TextChanged(ByVal sender As Object, 
ByVal e As System.EventArgs) Handles txtToDate.TextChanged
    if(Page.IsPostBack)
        Me.Grid.Visible = False
    End Sub
