hi,

I have three textboxes.in textbox1 am going to enter "om43 sai8" in textbox2 "87billa 8".

so now in textbox3 it should display both textbox values i mean to concatenate and here it should display only alphabets.

like "omsaibilla" in textbox3 on tabout it should happen...

any idea how to do this??

In your Add Button Event (to add the two input string) add following line of code :
I am also embedding the source code so that you can download it .

private void btnCalculate_Click(object sender, EventArgs e)
{
char[] text1;
char[] text2;
string result="";
int i,j;
//Converting input text into array
text1 = textBoxFirst.Text.ToCharArray();
text2 = textBoxSecond.Text.ToCharArray();
//for first input string
for(i=0;text1[i]!='\0';++i)
{
//trimming characters other tha alphabet
while(!((text1[i]>='a'&&text1[i]<='z')||(text1[i]>='A'&&text1[i]<='Z')||(text1[i]=='\0')))
{
for(j=i;j
{
text1[j] = text1[j + 1];
}
text1[j] = '\0';
}
}

//for second input string
for (i = 0; text2[i] != '\0'; i++)
{
//trimming characters other tha alphabet
while (!((text2[i] >= 'a' && text2[i] <= 'z') || (text2[i] >= 'A' && text2[i] <= 'Z') || (text2[i] == '\0')))
{
for (j = i; j
{
text2[j] = text2[j + 1];
}
text2[j] = '\0';
}
}

//Storing array into strings
string result1 = new string(text1);
string result2 = new string(text2);

//Concating two string
result = result1.Trim(new char[]{'\0'}) + result2.Trim(new char[]{'\0'});

//Showing result into textBox
textBoxResult.Text = result;

}

Hi,
you can also use Regex to remove number from the string
protected void btnOk_Click(object sender, EventArgs e)
{
TextBox3.Text= Regex.Replace(TextBox1.Text, "[0-9]", "") + Regex.Replace(TextBox2.Text, "[0-9]", "");

}
hope this will help you.

string s1 = TextBox1.Text;
string s2 = TextBox2.Text;
string s3 = s1 + "" + s2;
foreach (char c in s3)

You can use any event like page_Load and click events.
