我在GridView里面添加了一个模板列 里面是一个按钮
按钮的单击事件 protected void Button1_Click(object sender, EventArgs e)
从参数e里面无法获取 我单击的是那一行的按钮
因为不是GridViewCommandEventArgs e
那么我怎么获取单击的是那一行的序号啊 ???
按钮的单击事件 protected void Button1_Click(object sender, EventArgs e)

不能用 调用SqlDataSource1.Update()方法更新数据
但是在Gridview 里面自带的编辑,更新 可以更新数据啊 ??

大概知道你的意思了 你能给段代码让我理解下吗?
我不知道怎么实现啊
{
if (sender is Button)
{
Button btn = sender as Button;
........
}
}
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked.
if(e.CommandName=="Add")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
// Retrieve the row that contains the button clicked
// by the user from the Rows collection.
GridViewRow row = CustomersGridView.Rows[index];
// Create a new ListItem object for the customer in the row.
ListItem item = new ListItem();
item.Text = Server.HtmlDecode(row.Cells[2].Text);
// If the customer is not already in the ListBox, add the ListItem
// object to the Items collection of the ListBox control.
if (!CustomersListBox.Items.Contains(item))
{
CustomersListBox.Items.Add(item);
}
}
} void CustomersGridView_RowCreated(Object sender, GridViewRowEventArgs e)
{
// The GridViewCommandEventArgs class does not contain a
// property that indicates which row's command button was
// clicked. To identify which row's button was clicked, use
// the button's CommandArgument property by setting it to the
// row's index.
if(e.Row.RowType == DataControlRowType.DataRow)
{
// Retrieve the LinkButton control from the first column.
LinkButton addButton = (LinkButton)e.Row.Cells[0].Controls[0];
// Set the LinkButton's CommandArgument property with the
// row's index.
addButton.CommandArgument = e.Row.RowIndex.ToString();
} }

LinkButton addButton = (LinkButton)e.Row.Cells[0].Controls[0];
换为
LinkButton xxButton = (LinkButton )e.Row.Cells[0].FindControl("LinkButton_XXNR")
