Text format of textbox

[rick.ben15]

Hi experts,

I have a textbox with fixed length of 13. Now what I want to do is that if I enter 12345 the text should change to
0000001234500 (6 zeros + value + 2 zeros)), last 2 digit is for decimal value and the remaining 6 digit should be replace by
leading zeros. and if I enter 1234 than value should be 0000000123400 (7 zeros + value + 2 zeros).

Thanks

int a = txtabc.Length;
string strFirst="";
for(int i=0;i<13-a;i++)
{
strFirst+="0";
}

txtabc.Text = strFirst+ txtabc.Text;
