If you wanted it through javascript, then try this

XML

<script type="text/javascript" language="javascript">
    function capFirst(oTextBox) {
        oTextBox.value = oTextBox.value[0].toUpperCase() + oTextBox.value.substring(1);
               }
</script>
<asp:TextBox runat="server" onChange="javascript:capFirst(this);" ID="Tb1" AutoPostBack="False" />

The simplest way to do this would be when you submit the form. If you really want to do it as the user enters it, you can use the onkeyup event handler to change the data, but it's going to be more work to make sure that the cursor stays where the user put it (especially if they type in the middle of an existing word).

The Javascript logic for capitalization like this is pretty simple:

JavaScript

function capFirst(oTextBox) {
    var sText = oTextBox.value;
    sText = sText.substring(0,1).toUpperCase() + sText.substring(1,sText.length);
    oTextBox.value = sText;
    }

string myString = "tHis IS my tEXT";

TextInfo myTI = new CultureInfo("en-US",false).TextInfo;
myTI.ToTitleCase(myString);

Solution 1

In case if use winforms

C#

private void tb1_Leave(object sender, EventArgs e)
        {
         tb1.Text = tb1.Text.Substring(0, 1).ToUpper() + tb1.Text.Substring(1);
            }

Incase of aspnet

C#

private void tb1_TextChanged(object sender, EventArgs e)
        {
         tb1.Text = tb1.Text.Substring(0, 1).ToUpper() + tb1.Text.Substring(1);
            }

Dont forget to use Autopostback=true for the textbox in aspx

that is an event comes with each control.Check this http://msdn.microsoft.com/en-us/library/system.windows.forms.control.leave.aspx

Pradeep_kaushik 26-Sep-12 2:52am

this event is not shown in my event window

Santhosh Kumar Jayaraman 26-Sep-12 2:54am

OK sorry.I didnt see you were using aspnet.. Use textchanged event and write the same method
tb1.Text = tb1.Text.Substring(0, 1).ToUpper() + tb1.Text.Substring(1);

textbox_leave event is for winforms not for aspnet.
