GridviewCell十进制接受问题 [英] GridviewCell decimal accept issue

问题描述

如何像我对Textbox那样使Gridview单元格只接受一个小数点?

Hi,

how can I make Gridview cell from accepting only one decimal point like I did for Textbox?

private void txtDiscount_KeyPress(object sender, KeyPressEventArgs e)
{
  if (e.KeyChar == '.')
  {
    if (txtDiscount.Text.Contains('.'))
      e.Handled = true;
  }
}

但是对于gridview单元，它不起作用.您可以帮我吗?

But for the gridview cell it''s not working. Can you help me?

推荐答案

对于Gridview中的子控件，我们没有直接事件

所以首先我们必须获得像这样的TextBox值

For Child Controls in the Gridview we don''t have the direct events

so first we have to get the TextBox value like this

TextBox Foottxtboxunitrate = (TextBox)ProjectOnFormGrid.FooterRow.FindControl("Foottxtboxunitrate");

然后

then

Regex amountpattern = new Regex(@"^[0-9]*(\.)?[0-9]{0,1}?

" ); 如果(amountpattern.IsMatch(Foottxtboxunitrate.Text.Trim())== false ) { lblError.Text = " true ; Foottxtboxunitrate.Focus(); 返回； }

"); if (amountpattern.IsMatch(Foottxtboxunitrate.Text.Trim()) == false) { lblError.Text = "Enter valid Rate amount with maximum 1 decimal places. "; lblError.Visible = true; Foottxtboxunitrate.Focus(); return; }

您可以使用javascript
来实现
使用JavaScript进行GridView计算-格式设置和验证 [ ^ ]

You can achieve that by using javascript
