问题描述

在gridview中如下

In gridview as follows

           Compid   Companyname Address
Select       1        trom

Gridview选择的索引更改代码如下

Gridviewselected index change code as follows

protected void gvcomdet_SelectedIndexChanged(object sender, EventArgs e)
  {
      txt_compid.text = gvcomdet.SelectedRow.Cells[1].text.tostring();
      txt_name.text = gvcomdet.SelectedRow.Cells[2].text.tostring();
      txt_address.text = gvcomdet.SelectedRow.cells[3].text.tostring()
  }

当我在文本框中选择gridview gridview时，所选行将显示如下

When i click the select in gridview in textbox gridview selected row will be displayed as follows

Compid          1     (txt_compid)
Companyname     trom  (txt_name)
Address         <code>" "</code>

在地址文本框中，txt_address显示

i想要验证不应该显示在 txt_address 文本框中，它将被替换为空值

我怎样才能在asp.net中使用c＃验证。

In address textbox txt_address shows
i want to validate " " should not be shown in txt_address textbox it will be replaced with empty value

for that how can i validate in asp.net using c#.
