Problem with emphasis

[ericc34]

I have an radmaskedtextbox in my page and i want only character from a to z and A to Z without é, è, etc.

How I can do this ?

Hello Eric,

There is no easy way to create such mask. You have to list all possible symbols one by one. Sample code is shown below:

<telerik:RadMaskedTextBox ID="RadMaskedTextBox1" runat="server" AllowEmptyEnumerations="true">
</telerik:RadMaskedTextBox>

protected void Page_Load(object sender, EventArgs e)
{
    uint maxCharacters = 10;
    RadMaskedTextBox1.Mask = GenerateCustomMask(maxCharacters);
}

private string GenerateCustomMask(uint maxCharacters)
{
    uint startChar = '0';
    uint endChar = 'z';
    string outMask = "";
    StringBuilder mask = new StringBuilder();
    mask.Append("<");
    for (uint i = startChar; i <= endChar; i++)
    {
        if (Char.IsLetterOrDigit((char)i))
            mask.Append((char)i);
        else continue;
        if (i < endChar)
            mask.Append("|");
        else
            mask.Append(">");
    }
    for (uint i = 0; i < maxCharacters; i++)
        outMask += mask.ToString();
    return outMask;
}

Note that you may have a noticeable performance degradation on the client if you have too much symbols.
