好的，我有一个允许用户删除一行的 gridview，当用户单击删除链接按钮时，会发生回发。我得到按钮触发的行的索引，然后调用一个获取计数的存储过程。但在删除该行之前，将显示确认信息。问题是用户必须在确认对话框出现之前单击两次删除链接按钮。提前感谢您的帮助代码如下。
<asp:GridView ID="updtCompGrdVw" runat="server"
AutoGenerateColumns="False"
DataKeyNames = "GUID"
OnRowCancelingEdit="updtCompGrdVw_RowCancelingEdit"
OnRowEditing="updtCompGrdVw_RowEditing"
OnRowUpdating="updtCompGrdVw_RowUpdating"
OnRowDeleting="updtCompGrdVw_RowDeleting"
<RowStyle BackColor="White" />
<EmptyDataRowStyle Wrap="False" />
<Columns>
<asp:CommandField ShowDeleteButton="true" HeaderText="Delete" CausesValidation="false">
<HeaderStyle ForeColor="White" />
<ItemStyle HorizontalAlign="left" VerticalAlign="Top" Width="40px" Font-Bold="True" Font-Size="Small"/>
</asp:CommandField>
</Columns>
</asp:GridView>
protected void updtCompGrdVw_RowDeleting(Object sender, GridViewDeleteEventArgs e)
{
try
{
int index = Convert.ToInt32(e.RowIndex);
DataKey dtKey = updtCompGrdVw.DataKeys[index];
string DKpif_id = dtKey.Values["GUID"].ToString();// +", " + dtKey.Values["itmID"].ToString();
GridViewRow Row = updtCompGrdVw.Rows[index];
conn.Close();
SqlCommand cmd3 = new SqlCommand("StoreProcedureName", conn);
cmd3.CommandType = CommandType.StoredProcedure;
cmd3.Parameters.Add("@GUID", SqlDbType.NVarChar);
cmd3.Parameters["@GUID"].Value = DKpif_id;
conn.Open();
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds = new DataSet();
adapter.SelectCommand = cmd3;
adapter.Fill(ds);
if (ds.Tables.Count > 0)
{
Session["CntctCount"] = ds.Tables[0].Rows[0]["ContactsCount"].ToString();
(Row.Cells[Row.Cells.Count - 1].Controls[0] as LinkButton).OnClientClick = "if (!confirm('There are (" + Session["CntctCount"].ToString() + ") contacts associated with this company!, Are you sure you want to Delete this company?')) { return false; }";
ds.Clear();
conn.Close();
}
}
catch (SqlException ex)
{
}
}
