Question

I am having a treeview with some nodes. I am also having a panel. I have taken some usercontrol forms and i will load those usercontrols when corresponding node is selected from the child hood. Now what i need is have some validations like if i left the text box empty i will have some tooltips displayed to the user. Suppose if i click on first node i will have a user control loaded. With out giving any values if i hit ok i will have some tool tips as follows

Now if i select the second node from the tree still the tooltips getting displayed i would like to hide those

Any Help please

my code for rasing error tooltips is as shown below

   public class TestClass
    {
        public void RequiredText(TextBox txtTemp, ToolTip newtoolTip)
        {

            if (txtTemp.Text != string.Empty)
            {
                txtTemp.BackColor = System.Drawing.Color.White;
                newtoolTip.Hide(txtTemp);

            }
            else
            {
                txtTemp.BackColor = System.Drawing.Color.Tomato;
                newtoolTip.Show("Required", txtTemp);
            }
        }
    }

But this was done in the use control form.

Answer 1

Got the answer just written Usrcntrl_Leave event for every user control as

    private void usrcntrlPPD_Leave(object sender, EventArgs e)
    {
        this.Dispose();
    }

This solved my problem 🙂
