在GridView中更新 [英] updating in gridview

问题描述

当我通过gridview更新数据表时，它显示错误:"GridView''Gridview1''触发了未处理的事件RowUpdating".

解决方案

将aspx中的OnRowUpdating()事件简单地添加为:

 <   asp:gridview     id   ="   id   gvVehicle"   gvVehicle" span>    runat   =" 服务器" 自动生成列  错误"  cellpadding   ="     xmlns:asp   ="  > 
                                                    宽度="99％" ForeColor =#333333" GridLines ="None" CssClass ="allgrids" OnRowCommand ="gvVehicle_RowCommand"
                                                    OnRowUpdating ="gvVehicle_RowUpdating" ..... <  /asp:gridview   受保护的 无效 gvVehicle_RowUpdating(对象发​​件人，GridViewUpdateEventArgs e)
   {

   } 

这将解决您的错误

，同时从文本框中的gridview值中获取值为null，这样我就无法更新数据表....此问题的解决方案是什么? /blockquote>

When i''m updating the datatable via gridview it shows the error: "The GridView ''Gridview1'' fired event RowUpdating which was not handled".
How can i come out of this error?

解决方案

simple add OnRowUpdating() event in aspx as :

<asp:gridview id="gvVehicle" runat="server" autogeneratecolumns="False" cellpadding="4" xmlns:asp="#unknown">
                                                    Width="99%" ForeColor="#333333" GridLines="None" CssClass="allgrids" OnRowCommand="gvVehicle_RowCommand"
                                                    OnRowUpdating="gvVehicle_RowUpdating".....</asp:gridview>

and in aspx.cs add:

protected void gvVehicle_RowUpdating(object sender, GridViewUpdateEventArgs e)
   {

   }

this will solve your error

while taking value from gridview value in the textbox is null so that i can''t update the datatable.... what is the solution for this problem?
