推荐答案

使用gridview的行数据绑定方法，并在此方法中找到gridview单元格的控件，然后将文本框值与单元格值相乘.

Hi,

Use the row databound method of gridview and into this method find the control of the gridview cell and then multiply the textbox value with the cell value.

void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
 {
   if(e.Row.RowType == DataControlRowType.DataRow)
   {
     // Multiply the cell of gridview with the textbox value.
     e.Row.Cells[1].Text = (Convert.ToInt32(e.Row.Cells[1].Text) + Convert.ToInt32(textBox.Text)).ToString(); //put the cell number as position in your gridview
   }

 }

在gridview中添加以下事件.

< asp:gridview id ="GridView" onrowdatabound ="GridView_RowDataBound" runat ="server">
//您的gridview代码



希望这会对您有所帮助

In the gridview add the below event.

<asp:gridview id="GridView" onrowdatabound="GridView_RowDataBound" runat="server">
//Your gridview code



Hope this will help you

是的，您也可以通过Java脚本在文本框发生模糊事件时执行此操作，只需检查值是否为数值，然后将其乘以网格视图单元格值即可.
要使用JavaScript访问网格视图，请参考
