如何接受datagrid单元格中的数值 [英] How to accept numeric values in datagrid cell

问题描述

嗨

datagridcell只接受我在dgv_CellValidating下编写此代码的数字值，但它不能正常运行哪个事件

Hi
datagridcell Accept only numeric values i wrote this code under dgv_CellValidating,but its not working which event is currect

if (e.ColumnIndex == 4) // 1 should be your column index
{
    int i;

    if (!int.TryParse(Convert.ToString(e.FormattedValue), out i))
    {
        e.Cancel = true;
        label1.Text = "please enter numeric";
    }
    else
    {
        // the input is numeric
    }
}

推荐答案

仅在列中写数字

使用tb_keypress和dgv_EditingControlShowing事件

例如...
