Hi,

Go to the design page of your screen,there you can find the
FORM tag.

You can find the AutoComplete property.Then set that value as "OFF".
Thats it.

If this property is not showing in your page also just write this property manually.

Regards,
Kiran.

<asp:TextBox ID="TextBox1" AutoCompleteType="disabled" runat="server"></asp:TextBox>

Use This Function

public void EmptyControlData(Control parent)
    {
        foreach (Control c in parent.Controls)
        {
            if ((c.GetType() == typeof(TextBox)))
            {
                ((TextBox)c).Text = "";
            }
            if ((c.GetType() == typeof(DropDownList)))
            {
                ((DropDownList)c).SelectedIndex = -1;
                //((DropDownList)c).Items.Clear();
            }
            if (c.HasControls())
            {
                EmptyControlData(c);
            }
        }
    }

Here parent is this.

Hi,

This problem is called the Cacheing the browser data(Read Cache concept in ASP.NET).
You can solve this problem by making AutoComplete property of Form Tag of your page set as "OFF".

or

you need to clear the your page Cache data manually.

Kiran.
