禁用选项卡并在c＃中单击按钮时启用

Question

I have the this code to disable tab page:

private void tabControl_Selecting(object sender, TabControlCancelEventArgs e)
    {
        if (e.TabPage == tabPage)
        {
            e.Cancel = true;
        }
    }

and i want to enable it when a button is click. Is there a way to do it?

Answer 1

declare bool property in your form, something like this:

public Form1
{
   bool TabSelectingAllowed {get;set;}

when user clicks on button, change value

private void button1_Click(object sender, EventArgs e)
{
    TabSelectingAllowed = true;
}

in you existing code add additional checking for value of that property

private void tabControl_Selecting(object sender, TabControlCancelEventArgs e)
{
    if (e.TabPage == tabPage)
    {
       if (!TabSelectingAllowed)
           e.Cancel = true;
    }
}
