Hi Lokesh First you should add following controls to your user cntrol desinger. For Name : 1 TextBox 1 combo box (Let's say textbox1 and combobox1) For FirstName: 1 TextBox (let's say textbox2) For LastName: 1 TextBox 1 combo box (Let's say textbox3 and combobox3) For State: TextBox 1 (let's say textbox2) When you drag the controls to the designer drag them so that the locations of combobox1 and textbox1 are same. And aslo the locations of combobox3 and textbox3 are same. Then in the designer set combobox1 and combobox3 to visible = false Then in the checked_changed event of your check box 1 write following code. If(checkbox1.Checked) { //Yes is checked textbox1.Visible = false; textbox3.Visible = false; combobox1.Visible = true; combobox2.Visible = true; } else { //Yes is unchecked textbox1.Visible = true; textbox3.Visible = true; combobox1.Visible = false; combobox2.Visible = false; } If you have any problem pls ask. If you find this useful pls mark this as accepted.
