这是我的gridview:
<asp:GridView ID="gvconsumer" runat="server" AutoGenerateColumns="False" Width="50%" >
<Columns>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Label ID="lblid" runat="server" Text='<%# Bind("id") %>' Visible="false" ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Consumer">
<ItemTemplate>
<asp:Label ID="lblconsumer" runat="server" Text='<%# Bind("FirstName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:Label ID="lblname" runat="server" Text='<%# Bind("LastName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<asp:Label ID="lblstatus" runat="server" Text='<%# Bind("Status") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="DateCreated">
<ItemTemplate>
<asp:Label ID="lbldatecreaterd" runat="server" Text='<%# Bind("DateCreated") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Button ID="btnApprove" runat="server" Text="Approve" OnClick="btnApprove_Click" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Button ID="btnReject" runat="server" Text="Reject" OnClick="btnApprove_Click" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
这是我的代码:( AcceptButton)
if (btnApprove_Click)
GridViewRow row = ((Button)sender).Parent.Parent as GridViewRow;
string id = ((Label)row.FindControl("lblid")).Text;
Response.Write(row.RowIndex);
string ApprovedStatus = "Approved";
string status = ClassBiller.ConsumerStatus(int.Parse(id), ApprovedStatus, DateTime.Now);
这是ConsumerStatus()的数据层:
string retUpdateStatus = "";
string consumerStatus = "UPDATE MerchantConsumer SET Status = @Status, DateAccepted = @DateAccepted WHERE ConsumerID = @Consumerid";
string[] param = { "@Consumerid", "@Status", "@DateAccepted" };
object[] paramVal = { ConsumerID, Status, DateAccepted };
try
{
ClassDBQuery.ExecNonQuery(consumerStatus, param, paramVal);
}
catch (Exception ex)
{
throw ex;
}
return retUpdateStatus;
这就是GridView的绑定方式:
DataTable gridViewConsumer = new DataTable();
gridViewConsumer = ClassConsumer.GetRows();
gvconsumer.DataSource = gridViewConsumer;
gvconsumer.DataBind();
我的问题是,我必须双击按钮更新gridView的状态字段。但是当我检查数据库时(第一次点击),状态字段已经更新.. 请帮助....

成功进行数据库操作后,您需要再次绑定网格。
