As far as I am getting your query, you just want to check whether a textbox is empty or not..
Make a method and call it on button_clicl -
Eg -
private String CheckTextBox()
{
try
{
if(txtbox1.text.Lenght > 0)
{
if(txtbox2.text.lenght > 0)
{
return null;
}
else return "Enter value in text box 2";
}
else return "Enter value in textbox1";
}
catch(Exception err){return err.Message.ToString();}
}
---
On Button_Click
If(CheckTextBox() == null)
{
//proceed
}
else errormessage = CheckTextBox().ToString().Trim();
