我在
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "EditRole ")
{
string m_Login = " ";
m_Login = GridView1.DataKeys[GridView1.Rows..DataItemIndex].Value.ToString();
currencyLib.ShowMessage(this, " ",m_Login);
}
}
提示
未将对象引用设置到对象的实例。

源错误:
行 34: {
行 35: string m_Login = " ";
行 36: m_Login = GridView1.DataKeys[GridView1.SelectedRow.DataItemIndex].Value.ToString();
行 37:
行 38: currencyLib.ShowMessage(this, " ",m_Login);
[解决办法]
string MessageID = gvMessage.DataKeys[e.Row.RowIndex][0].ToString();
[解决办法]
2005里面
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
string pid = GridView1.SelectedDataKey.Value.ToString();
if (cart != null)
{
cart.DeleteItem(pid);
Profile.ShoppingCart.DeleteItem(pid);
Total.Text = String.Format( "合计:{0:c} ", cart.TotalCost);
//删除后的绑定,下面可以不要因为Page_Load事件绑定了
//ShoppingCart cart = (ShoppingCart)Session[ "MyShoppingCart "];
//GridView1.DataSource = cart.Orders;
GridView1.DataBind();
}
}
[解决办法]
this.GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Value
