I want the system to ignore the disabled textboxes when validating the input length.

Question

4.00/5 (1 vote)

See more:

txtFaxNo.Text, txtTelNo.Text, and txtMobileNo.Text are textboxes that has to be enabled to be validated. But when they are disabled, I want the system to ignore them when validating the length.

C#

if ((myControl.Text.Length != 7) && (myControl.Name.ToString() == "txtTelNo") && (myControl.Enabled)).

The code above didn't work. the system still validates the length of disabled textbox.

where in the code can I insert " mycontrol.Enabled "?

C#

public static bool IsValidLength(Form myform)
        {
            foreach (Control myControl in myform.Controls)
            {
              
                if (myControl.GetType() == typeof(TextBox))
 
                {
 
                        if (IsNumeric(myControl.Text) == true)
                        {
                            if ((myControl.Text.Length != 7) && (myControl.Name.ToString() == "txtTelNo"))
                            {
                                MessageBox.Show(myControl.Name.Substring(3).ToString() + " length is invalid.");
                                myControl.Focus();
                                return false;
                            }// end of 7
                            if ((myControl.Text.Length != 7) && (myControl.Name.ToString() == "txtFaxNo"))
                            {
                                MessageBox.Show(myControl.Name.Substring(3).ToString() + " length is invalid.");
                                myControl.Focus();
                                return false;
                            }// end of 7
                            if ((myControl.Text.Length != 11) && (myControl.Name.ToString() == "txtMobileNo"))
                            {
                                 //myControl.Text = myControl.Text.Trim();

                                MessageBox.Show(myControl.Name.Substring(3).ToString() + " length is invalid.");
                                myControl.Focus();
                                return false;
 
                            }// end of 7

                        }// end of isnumeric

                        else
                        {
                            if ((myControl.Text.Length < 2) && (myControl.Name.ToString() != "txtSuppNo"))
                            {
                                MessageBox.Show(myControl.Name.Substring(3).ToString() + " length is invalid.");
                                myControl.Focus();
                                return false;
                            }// end of 2
                        }// end of else

                }//end of gettype
            }//end of foreach
            return true;

Hi,

Here is one of the solution,

1) You need to use ASP.NET validation control instead of manual validation from codebehind.
2) You need to assign validation group property from code behind.

Thanks

Solution 2

Use this. Look for change in paranthesis

if ( 
((myControl.Text.Length != 7)
 && (myControl.Enabled)) && 
(myControl.Name.ToString() == "txtTelNo")

)
