At first I have taken some string in which I am trying to save the input values of textboxs and there is a combo box, I am trying to save the input value of the combo box to database, but this following code is unable to do that !!! what is the prob please help me.
private void OK_Click(object sender, EventArgs e)
{
string sTxtcmpnyName = "";
string sTxtcmpnyAdd = "";
string sPhoneno = "";
string sTxtFax = "";
string sPanNo = "";
string sTxtTin = "";
string sTax = "";
string sAccYr = "";
string sComboSt = "";
foreach (Control c in this.Controls) ////*Adding Validation to the textbox.*// // Here the control is entered into GroupBox Grpcmp where c is denoting the name of the control into the groupbox.
{
// c1 is another control which denotes the textboxes under the GroupBox Grpcmp.
foreach (Control c1 in c.Controls)
{
/////Now this following code snippets reperesents that the name of the company should not be blank.
if (c1 is TextBox == true) // simpler that what you've done there
{
TextBox temp = (TextBox)c1;
//The control is entering into Txtcompany.
if (temp.Name == "Txtcompanyname")
{
//Condition checking is the TextBox is empty or Null then the following message will be shown.
if ((temp.Text == "") || (temp.Text == "NULL"))
{
MessageBox.Show("Company Name should not be Blank");
}
sTxtcmpnyName = temp.Text;
}
else if (c1.Name == "TxtcompanyAddress")
{
sTxtcmpnyAdd = c1.Text;
}
else if (c1.Name == "Txtphoneno")
{
sPhoneno = c1.Text;
}
else if (c1.Name == "TxtFax ")
{
sTxtFax = c1.Text;

{
sTxtTin = c1.Text;
}
else if (c1.Name == "Txtservicetax")
{
sTax = c1.Text;
}
//Now I am converting the TxtAcYr into Date format.
//For this purpose two conditions are checked first.
//First If the TextBox TxtAcYr is Null or empty it will show the message to enter the accountyear!!
//Second If the length of the TextBox TxtAcYr is less than 10, it will again generate a message The date format should be in DD/MM/YYYY
// Then the value of the use input will be picked using a For loop.
if (c1.Name == "TxtAcYr")
{
sAccYr = c1.Text;
//Here a string is taken named as yearlength and the value of the TxtAcYr is assigned to it by using control c1.
//Condition Checking If the TextBox TxtAcYr is Null or empty it will show the message to enter the accountyear!!
if ((c1.Text == "") || (c1.Text == "NULL"))
{
MessageBox.Show("Account Year should be entered!!");
}
//Condition 2 is checking. Here the length of the string yearlength is whether equals to 10 or not is checked.
//Because there are total 10 characters in Date Format along with special character.
else
// MessageBox.Show(yearlength.Length.ToString());

//Now the value of user will be picked by using the code snippets.
else

{
//This condition is checking special characters.
//The positions of special characters(Here '-') are placed at 2nd and 5th numbers.
//So, the value of i can not be equals to 2 && 5.
