用户键入时，ColumnGridView中的千位分隔符带有逗号

Question

I am gonna to separate numbers with comma, What I am seeking is exactly like this

Comma Separator in c#

but the solution in that question did not work for me as I am doing this in column in gridview instead of textbox.

What I have done till now (part of the class for columns in a gridview):

public override string Text
{
    get { }
    set { base.Text = GetFormattedText(value); }
}

protected override void OnTextChanged(System.EventArgs e)
{
    base.OnTextChanged(e);
    Text = GetFormattedText(Text);
}

protected virtual string GetFormattedText(string text)
{
    string strText = text.Replace(",", "");
    decimal decValue = System.Convert.ToDecimal(strText);
    strText = decValue.ToString("#,##0");
    return strText;
}

So what happen with this piece of code:

when I am typing 12345 in column it becomes ---> 51,234

Pleae if my sayings are not clear tell me and I will explain it more

Answer 1

The problem is that when you change the textbox text, the caret goes to the first position of the TextBox . So after setting the TextBox text with the formatted text, you must add this line to go to the end:

base.SelectionStart = base.Text.Length;
