Changing the visible property server side not working

[Ryan]

I have a RadNumericTextbox where the visible field is set to false. Depending on another variables value, the  RadNumericTextbox visible may change to true. This is not working. The field is in a panel.

I stepped through the code and the visible property will not change.

I even directly changed the value to true and the value remained false in the watch list.

Hello Ryan,

I tested with the following code based on the provided details, and I was able to manipulate the Visible property of the NumericTextBox: 

<asp:Panel ID="panel1" runat="server">
    <telerik:RadNumericTextBox ID="numerbox1" runat="server" />
</asp:Panel>

<telerik:RadCheckBox ID="checkbox1" runat="server" OnCheckedChanged="checkbox1_CheckedChanged" />

protected void checkbox1_CheckedChanged(object sender, EventArgs e)
{
    RadCheckBox checkBoix = (RadCheckBox)sender;

    if (checkBoix.Checked == true)
    {
        numerbox1.Visible = true;
    }
    else if (checkBoix.Checked == false)
    {
        numerbox1.Visible = false;
    }
}

Note that this is just a guess of what the actual code used in your scenario is, and I'd like to ask you to adjust it to match the actual code, causing this odd behavior.

Kind regards,
Vasko
