HOw to set tabstop=false of controls on certain conditions.

Hi then you use this in your text change event
like thais
 protected void OnTextChanged_FirstName(object sender, EventArgs e)
    {

        getNameFormUi();

    }
private void getNameFormUi()
{foreach (Control c in Page.Controls)
    {
        foreach (Control childc in c.Controls)
        {
            if (childc is TextBox)
            {
                if(!string.isnullorEmpty(childc.Text)
                childc.text.tabstop=false;
            }
        }
    }}

Hi u can create this method outside and call this method in if you want then in OnTextChanged
or in Page load after all the controls are filled then u call the method.

Hi you can try like this
 foreach (Control c in Page.Controls)
    {
        foreach (Control childc in c.Controls)
        {
            if (childc is TextBox)
            {
                if(!string.isnullorEmpty(childc.Text)
                childc.text.tabstop=false;
            }
        }
    }

You can set all the controllers Tabstop to false using this.Controls.setAllControlsTabstop(false). But for each control, you have to use OnTextChanged.
