Keep Button Disabled after redirect using C# and VB.Net in ASP.Net

Hi suhaas121,

In order to achieve this you need to set a Session variable to store either enable or disable the Button.

When Button needs to be enable set the Session variable to true and when disable set it to false.

Then on PageLoad set the Button enabled property from Session.

Refer below example.

HTML

Default

<asp:Button ID="btn1" Text="Button 1" runat="server" OnClick="Button1_Click" />
<asp:Button ID="btn2" Text="Button 2" runat="server" OnClick="Button2_Click" />
<asp:Button ID="btnRedirect" Text="Redirect" runat="server" OnClick="OnRedirect" />

Home

<asp:Button Text="Back" runat="server" OnClick="OnBack" />

Code

Default

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["IsEnable"] != null)
    {
        btn1.Enabled = (bool)Session["IsEnable"];
    }
}

protected void Button1_Click(object sender, EventArgs e)
{
    Session["IsEnable"] = false;
    btn1.Enabled = (bool)Session["IsEnable"];
}

protected void Button2_Click(object sender, EventArgs e)
{
    Session["IsEnable"] = true;
    btn1.Enabled = (bool)Session["IsEnable"];
}

protected void OnRedirect(object sender, EventArgs e)
{
    Response.Redirect("Home.aspx");
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    If Session("IsEnable") IsNot Nothing Then
        btn1.Enabled = CBool(Session("IsEnable"))
    End If
End Sub

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
    Session("IsEnable") = False
    btn1.Enabled = CBool(Session("IsEnable"))
End Sub

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As EventArgs)
    Session("IsEnable") = True
    btn1.Enabled = CBool(Session("IsEnable"))
End Sub

Protected Sub OnRedirect(ByVal sender As Object, ByVal e As EventArgs)
    Response.Redirect("Home.aspx")
End Sub

Home

C#

protected void OnBack(object sender, EventArgs e)
{
    Response.Redirect("Default.aspx");
}

VB.Net

Protected Sub OnBack(ByVal sender As Object, ByVal e As EventArgs)
    Response.Redirect("Default.aspx")
End Sub
