Question

聽到我發佈了我的網格視圖。

   <Columns> 
        <asp:TemplateField HeaderText="Item"> 
          <ItemTemplate> 
           <p> <asp:Label ID="lblproductname" display="Dynamic" runat="server" Text='<%# Bind("productname") %>'></asp:Label></p> 
           <p><asp:Label ID="lblProductWeight" display="Dynamic" runat="server" Text='<%# Bind("groupvalue") %>'></asp:Label></p> 
           <p> <asp:Label ID="lblProductType" display="Dynamic" runat="server" Text='<%# Bind("groupname") %>'></asp:Label></p> 
          </ItemTemplate> 
          <HeaderStyle HorizontalAlign="Left" /> 
          <ItemStyle HorizontalAlign="Left" /> 
         </asp:TemplateField> 
        <asp:BoundField DataField="Quantity" HeaderText="Qty"> 
         <HeaderStyle HorizontalAlign="Left" /> 
        </asp:BoundField> 
        <asp:BoundField DataField="Price" HeaderText="Price"> 
         <HeaderStyle HorizontalAlign="Left" /> 
        </asp:BoundField> 
        <asp:BoundField DataField="SubTotal" HeaderText="Sub Total"> 
           <HeaderStyle HorizontalAlign="Left" /> 
          </asp:BoundField> 
       </Columns> 
       <FooterStyle CssClass="datatable" /> 
      </asp:GridView> 

因此如何使標貼的可見假的ItemTemplate programaticaly在XYZ方法

Answer 1

在Rowcommand你可以隱藏或網格顯示，例如項目模板：

void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e) 
    { 

    if(e.Row.RowType == DataControlRowType.DataRow) 
    { 
     //Your Condition 
     Label lblproductname = (Label)e.Row.FindControl("lblproductname") 
     If(a > B) 
     lblproductname.Visible = true; 
     //Others Lables 
     .... 

    } 

    } 

我希望有所幫助。

Answer 2

protected void OnRowCreated(object sender, GridViewRowEventArgs e) 
{ 
     e.Row.Cells[columnIndex].Visible = false; 
} 

唯一的解決方法我可以建議是給在aspx頁的HeaderText，然後找到使用。

protected void xyz() 
{ 
    ((DataControlField)youGridView.Columns 
      .Cast<DataControlField>() 
      .Where(fld => fld.HeaderText == "your header text") 
      .SingleOrDefault()).Visible = false; 
}

我相信您的問題在這裏得到解答：

How to find control in TemplateField of GridView?

從答案複製：

foreach(GridViewRow row in GridView1.Rows) { 
    if(row.RowType == DataControlRowType.DataRow) { 
     Label myLabel = row.FindControl("myLabelID") as Label; 
     myLabel.Visible = false; 
    } 
} 

從RowDataBoundEvent：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if(e.Row.RowType == DataControlRowType.DataRow) 
    { 
     Label myLabel = e.Row.FindControl("myLabelID") as Label; 
     myLabel.Visible = false; 
    } 
}
