推荐答案

使用GridView RowCommand事件，

在那种情况下，您可以试试这个

if(e.CommandName =="EditPage")

Hi,
Use GridView RowCommand event,

In that event you can try this

if(e.CommandName== "EditPage")

//here you can make session eg Session["id"]=e.CommandArgument

//or can pass CommandArgument to QueryString

//and based on it retrieve data on textboxes on edit.aspx

Respone.Redirect("Edit.aspx);

Respone.Redirect("Edit.aspx);

在事件中

protected void btndelete_Click(object sender, EventArgs e)
{
   Button btn = (Button)sender;
   GridViewRow row = (GridViewRow)btn.NamingContainer;
 //do with your selected row what you want
}

在按钮上单击，将特定行的所有值保存在会话变量中
然后在第二页的页面加载中，使用这些会话变量填充不同的文本框.喜欢

On button click save all the values of particular rows in session variables
and on page load of second page fill the disered textboxes with these session variables. like

protected void imgbtnedit_Click(object sender, EventArgs e)
{
  GridViewRow Row=((Button)sender).Parent.Parent as GridViewRow;
  int index=Row.RowIndex;
  Session["Value1"]=((Label)grdpages.Rows[index].FindControl("ValueOfColumns1")).Text;
Session["Value2"]=((Label)grdpages.Rows[index].FindControl("ValueOfColumns2")).Text;
...
...
...
Response.Redirect("editpage.aspx");
}

并在页面上加载editpage.aspx

and on page load of editpage.aspx

textbox1.text=Convert.ToString(session["value1"]);
...
...
