You can handle TextChanged event of textbox. put a condition there, when limit reached then transfer focus to other textbox.

Hi Ankit,

I hope you want this,

Two text boxes, TextBox1 and TextBox2 with limit 4 respectively.
If I type 4 characters in TextBox1 then automatically focus should move to TextBox2.
For example,
If I want to type 12345678.
I type 1234 in TextBox1, When I press 5, focus should point to TextBox2 and 5678 should be entered in TextBox2, am i right?
If am right then here is the code for you

C#

private void textBox1_TextChanged(object sender, EventArgs e)
       {
           //validates the length of textbox starts from 0.
           if (textBox1.TextLength > 3)
           {
               textBox2.Focus();
           }
       }

I hope this would help you a bit.

Regards,
RK

It is very easy to do this, just use the following code:

private void textBox1_TextChanged(object sender, EventArgs e)
{
   // Determine the number of characters typed into textbox1, 
   // if greater than 5, go to textbox2            
   if(textBox1.TextLength == 5)
   {
       // textbox2 becomes the active textbox            
       textBox2.Focus();
   }
}

Note: you must use the double equals (==) for it to work, don't try to use the greater than (>) symbol.

Reasons for my downvote:
- Comment says "if greater than 5, go to textbox2 " but code says "if exactly equal to 5, go to textbox2".
- Your words "you must use the double equals (==) for it to work, don't try to use the greater than (>) symbol." is absolute tosh
- You have essentially just repeated Solution 2 posted 7 years ago

Hi
It is really easily just do it :

C#

<pre lang="cs">private void textBox1_TextChanged(object sender, EventArgs e)
{

    if (((TextBox)sender).TextLength > 5)
        SendKeys.Send("{Tab}");
}

Just remember you should set TabIndex for your controls.

Best Regards.

I think you want export your data from gridview to table in sql server so if my understand is true you don`t need to the any automatically action you can do it with dataset very easily just read ever row in your datagrid or dataset and generate Insert Sql command ;)

No Buddy.
Just! Like my application enter text in one column, many characters in that column, but client requirement is that column should be break column value automatically moving to next column when limit is reached.
It is only apply for select query.

That string will be enter only one column, but display in four column after one column value is reached then same is Second and third column.
