如何在vb.net中获取选定的gridview列索引 [英] How to get selected gridview column index in vb.net

问题描述

先生，我需要知道所选的gridview列索引。在gridview_rowdeleting函数上。

这是我的代码： -

 <   asp：GridView     ID   =  GridView1    CssClass   =  mGrid < span class =code-attribute>   AutoGenerateColumns   =  False    BackColor   =  白色  
   
                                                       EmptyDataText  < span class =code-keyword> = 没有学生nt    HeaderStyle-Horizo​​ntalAlign   = 左   宽度  =  100％    runat   =  server >  
 <  列 >  
 
 <   asp：TemplateField     HeaderText   =  WeekDayID    SortExpression   =  WeekDayID   可见   < span class =code-keyword> =  false     >  
 <   ItemTemplate  >  
 <   asp：标签    ID   =  LabelWeekDayID    runat   =  server   正文  ='  <％ #Eval（   WeekDayID）％> '    可见    =  false   >  <   / asp：标签 >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 
 <   asp：TemplateField       HeaderText   = 天/期      HeaderStyle-Width   =  60px      ItemStyle-Width   =  60px >  
 <   ItemTemplate中 >  
 <   asp：标签    ID   =  Label1    runat   =  server   文字  ='  <％＃ Eval（  DayName）％> '     宽度 < span class =code-keyword> =  60px   >  <   / asp：标签 >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 
 
 <   asp：TemplateField       HeaderText   = 我 < span class =code-attribute>     HeaderStyle-Width   =  120px    ItemStyle-Width   =  120px   >  
 <   ItemTemplate  >  
 <   asp：Label     ID   = < span class =code-keyword> LblI    runat   =  server   文字  ='  <％ #Eval（  I）％> '   宽度  =  100px    CommandName   = 选择  >  <   / asp：Label  >  
 <   asp：ImageButton     ID   =  ImageDelete1    runat   =  server    CommandName   = 删除    ImageUrl   = 〜/ Images / Delete.png   宽度  =  20px   高度  =  20px    /  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  < span class =code-keyword>>  
 
 <   asp ：TemplateField       HeaderText  < span class =code-keyword> =  II      HeaderStyle-Width   =  120px    ItemStyle-Width   =   120px   >  
 <   ItemTemplate  >  
 < span class =code-keyword><   asp：Label     ID   =  LblII    runat   =  server    文字  =' < span class =code-keyword> <％ #Eval（  II）％> '   宽度  =  100px   >  < ;   / asp：标签 >  
 <   asp：ImageButton     ID   =  ImageDelete2    runat   =  server    CommandName   = 选择    ImageUrl   =  〜/ Images / Delete.png   宽度  =  20px   高度  =   20px    /  < span class =code-keyword>>  
 <   / ItemTemplate  >  
 <   / asp： TemplateField  >  
 
 
 
 <   /列 >  
 
 <   / asp：GridView  >  

 受保护  Sub  GridView1_RowDeleting（ ByVal  sender  As  < span class =code-keyword> Object ， ByVal  e  As  System.Web。 UI.WebControls.GridViewDeleteEventArgs）句柄 GridView1.RowDeleting 
  Dim  WeekDayID 作为 字符串 =  CType （GridView1.Rows（e.RowIndex）。 FindControl（  LabelWeekDayID），Label）.Text 
 
 结束  Sub  

我尝试了什么：



i获取所选行索引但我想知道还选择了gridview列索引。

解决方案

尝试使用 DataGridView.CurrentCell .ColumnIndex

sir, i need to know selected gridview column index. on gridview_rowdeleting function.
here is my code:-

<asp:GridView ID="GridView1" CssClass="mGrid" AutoGenerateColumns="False" BackColor="White"

                          EmptyDataText="No Student" HeaderStyle-HorizontalAlign="Left" Width="100%" runat="server">
                          <Columns>

                            <asp:TemplateField HeaderText="WeekDayID" SortExpression="WeekDayID" Visible ="false"  >
                            <ItemTemplate>
                            <asp:Label ID="LabelWeekDayID" runat="server" Text='<%#Eval("WeekDayID") %>' Visible ="false" ></asp:Label>
                            </ItemTemplate>
                            </asp:TemplateField>

                            <asp:TemplateField  HeaderText="Days/Periods"  HeaderStyle-Width="60px"  ItemStyle-Width="60px">
                            <ItemTemplate>
                            <asp:Label ID="Label1" runat="server" Text='<%#Eval("DayName") %>'  Width="60px" ></asp:Label>
                            </ItemTemplate>
                            </asp:TemplateField>


                             <asp:TemplateField  HeaderText="I"  HeaderStyle-Width="120px" ItemStyle-Width="120px" >
                            <ItemTemplate>
                            <asp:Label ID="LblI" runat="server" Text='<%#Eval("I") %>' Width="100px" CommandName="Select"></asp:Label>
                            <asp:ImageButton ID="ImageDelete1" runat="server" CommandName="Delete" ImageUrl="~/Images/Delete.png" Width="20px" Height="20px" />
                            </ItemTemplate>
                            </asp:TemplateField>

                            <asp:TemplateField  HeaderText="II"  HeaderStyle-Width="120px" ItemStyle-Width="120px" >
                            <ItemTemplate>
                            <asp:Label ID="LblII" runat="server" Text='<%#Eval("II") %>' Width="100px" ></asp:Label>
                            <asp:ImageButton ID="ImageDelete2" runat="server" CommandName="Select" ImageUrl="~/Images/Delete.png" Width="20px" Height="20px" />
                            </ItemTemplate>
                            </asp:TemplateField>



                          </Columns>

                      </asp:GridView>

Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
    Dim WeekDayID As String = CType(GridView1.Rows(e.RowIndex).FindControl("LabelWeekDayID"), Label).Text

End Sub

What I have tried:

i get the selected row index but i want to know also selected gridview column index.

解决方案
