How Do I: Get the text value from the ((TextBox)sender)?

Gustavo

Hello:

I am writing my own validation routine and I need to get some information from the TextBox that I am coming from.

I am using: ((TextBox)sender).Name.ToString() To get the name of the TextBox.
Is there a way to get the Text Value of the TextBox? I know if I do a: ((TextBox)sender) It will give me: "System.Windows.Forms.textBox, Text: Company" The Value that I want is the "Company". I guess it I can parse it and get it, but is there a simpler way like the: ((TextBox)sender).Name.ToString() ?

Using text box's Validating event you can validate the textbox..

suppose if you want to check the textbox only accept numeric value:

private void txtid_Validating(object sender, CancelEventArgs e)
   {
   TextBox tb;
   tb = (TextBox)sender;
   if (!IsNumeric(tb.Text.ToString()))
   {
   MessageBox.Show("ID Should Be Numeric!");
   txtid.Focus();
   return;
   }

   }

After looking at your sample... I figured it out. Thanks.

To get the name of the TextBox I did a: TheField_ID = ((TextBox)sender).Name.ToString().Substring(7);

To get the value in the TextBox I did a: TheValue = ((TextBox)sender).Text;

Thanks

I created a control class that will do the testing and it works for many type of variables. But I have to send it the value of the textBox.
