[WPF]如何让输入的字符自动变为大写

我用了以下代码：但是不成功。

worksheet.CellEditCharInputed += (s,e) =>
{
    if(e.InputChar >= 'a' && e.InputChar <= 'z')
    {
        e.InputChar = Char.ToUpper(Convert.ToChar(e.InputChar));
    }
};

以上代码在winform中可以，请问是wpf的bug吗？

使用的是1.2.0

Re: [WPF]如何让输入的字符自动变为大写

I just did this in the WPF version 1.2.2

The problem you had was you didn't convert the char to integer value that the e.inputchar uses, since use ASCII numbers.

What you have to do is convert the Char to ASCII number then check it with the e.inputchar.

Try this code.. I just got to work and i change your convert toupper

worksheet.CellEditCharInputed += (s,e) =>
{
    if(e.InputChar >= AscW('a') && e.InputChar <= AscW('z'))
    {
        e.InputChar = AscW(Convert.ToChar(e.InputChar).ToString.ToUpper);
    }
};

you could do like this too

worksheet.CellEditCharInputed += (s,e) =>
{
    if(e.InputChar >= 97 && e.InputChar <= 122)
    {
        e.InputChar = AscW(Convert.ToChar(e.InputChar).ToString.ToUpper);
    }
};

Re: [WPF]如何让输入的字符自动变为大写

hi, Shane
    thanks for your help.
    I do the same, but it still not work.

            worksheet.CellEditCharInputed += (s, e) =>
            {
                if (e.InputChar >= AscW('a') && e.InputChar <= AscW('z'))
                {
                    e.InputChar = AscW(Char.ToUpper(Convert.ToChar(e.InputChar)));
                }
            };

   
    and the AscW function:

        private int AscW(char p)
        {
            return (int)p;
        }

I also try the next code. still not work.

            worksheet.CellEditCharInputed += (s, e) =>
            {
                if (e.InputChar >= AscW('a') && e.InputChar <= AscW('z'))
                {
                    e.InputChar = 65;
                }
            };

Thanks Shane! This works in Windows Form edition but doesn't work in WPF. We'll try to fix the WPF edition from next release.

Re: [WPF]如何让输入的字符自动变为大写

Hello Jing and adams_mfsor,
       If use this code, in Wpf it works, but only works if you press F2 or double click with the mouse, if you type with your keyboard the cellinputedchar event does not fire. this the also the same as my other code. Sorry i was trying convert from VB.net solution, but i did it in C# this time both times i used WPF.

I did use the same code in winforms and it work fine, when you type the cellinputedchar event fires..

So, adams_mfsor, you can use this in WPF but have press F2 or double click to put the sheet into edit mode or maybe, you can use  BeforeCellKeyDown event that puts the cell in edit mode then end the edit when the cellinputedchar event done firing.

Tried to do it but keep giving null reference when use BeforeCellKeyDown and AfterCellKeyDown Event.
