Hey team. I developed a small win forms that has a tab control for switching between tab pages.The form consists of two tab pages.
Thanks in advance for the help.

Criteria what i need:

1. tab pages should not get selected on mouse click

What I have tried:

Code for disabling the manual selection of tab.(NOT WORKING)

C#

 private void tabControl1_Click(object sender, EventArgs e)
        {            
           if (tabControl1.SelectedTab == tabPage2)
{
tabControl1.SelectedTab = tabPage1;
MessageBox.Show("You don’t have permission !!");
}   

else if(tabControl1.SelectedTab == tabPage1)
{
tabControl1.SelectedTab = tabPage2;
MessageBox.Show("You don’t have permission !!");
}   
   }

Code for redirecting from tabpage1 to tabpage2(WORKING GOOD)

C#

 private void t1NextTabRedirectButton_Click(object sender, EventArgs e)
        {    
            tabControl1.SelectedTab = tabPage2;
}

Solution 1

Try it like this :

C#

public class myTabControl : TabControl
{
    protected override void OnSelecting(TabControlCancelEventArgs e)
    {
        e.Cancel = true;
        base.OnSelecting(e);
    }

    protected override void OnMouseClick(MouseEventArgs e)
    {
        MsgBox("! No Permission !");
    }

}

In the above code you are trying to cancel the mouse click. I tried your code and i don't fetch with any positive result.. Any other way?? Small changes made to my code which i had changed abouve. Kindly see to it

I don't understand ...
Of course ... you could select the 2nd TabPage ... but the Control doesn't switch to it ...
So if this code-snippet isn't the thing you need ... what do you need exactly ?

I made a little change - perhaps you take a look on it.
Now the Control raises not longer the MouseClick-Event ...

Solution 2

C#

private void tabControl_MouseDown(object sender, MouseEventArgs e)
{
    if (tabControl.SelectedTab == tabPage2)
{
tabControl.SelectedIndex = 0;
tabControl.SelectedTab = tabPage1;
MessageBox.Show("Action Denied!!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
      else if (tabControl.SelectedTab == tabPage1)
{
tabControl.SelectedTab = tabPage2;
MessageBox.Show("Action Denied!!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}

There is no response in the above code which you had sent. Is there any other solution?

Samuel Corpuz 4-Jan-18 23:57pm

Did you try to edit it?

go to the event of mousedown of your tabcontrol
then you will prompt to tabControl1_Mousedown

copy and paste this it will be fix
if (tabControl1.SelectedTab == tabPage2)
{
tabControl1.SelectedTab = tabPage1;
MessageBox.Show("You don’t have permission !!");
}

else if(tabControl1.SelectedTab == tabPage1)
{
tabControl1.SelectedTab = tabPage2;
MessageBox.Show("You don’t have permission !!");
}
