更新面板工作不正常

Question

我包裹着我的更新面板內的GridView，並設置觸發搜索按鈕，但它不能正常工作， 當我把文本到文本框，然後點擊搜索，然後GridView中顯示相關的結果，這是確定，但它應該通過單擊Gridview的SELECT按鈕將列的文本加載到文本框中，該按鈕在放置更新面板之前工作，但不是現在。它不會將文本加載到文本框中，也不會在單擊「搜索」按鈕後再次加載文本。

CODE：

<asp:UpdatePanel ID="UpdatePanel2" runat="server"> 
       <Triggers> 
        <asp:AsyncPostBackTrigger ControlID="btnSearch" EventName="Click" /> 
       </Triggers> 
       <ContentTemplate> 
        <asp:GridView ID="gridViewComplaints" AutoGenerateSelectButton="true" runat="server" CssClass="mGrid" OnSelectedIndexChanged="gridViewComplaints_SelectedIndexChanged"> 
       <EmptyDataRowStyle BorderStyle="None" ForeColor="Red" BorderWidth="0px" /> 
       <EmptyDataTemplate> 
        No Data Found for this Input. Try Again. 
       </EmptyDataTemplate> 
      <SelectedRowStyle CssClass="selected-row" BackColor="YellowGreen" ForeColor="white" /> 
      </asp:GridView> 
       </ContentTemplate> 
      </asp:UpdatePanel> 

protected void gridViewComplaints_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     GridViewRow row = gridViewComplaints.SelectedRow; 
     txtComplaintSubject.Text = row.Cells[2].Text; 
     HiddenFieldComplaintID.Value = row.Cells[1].Text; 
     int cid = Convert.ToInt32(HiddenFieldComplaintID.Value); 
     Response.Write(cid.ToString()); 
     gridViewComplaints.Visible = false; 

    } 

Answer 1

這是怎麼對我的作品。如果你可以試試這個代碼：

<asp:UpdatePanel ID="UpdatePanel2" runat="server"> 
    <ContentTemplate> 
     <asp:GridView ID="GridView1" class="gridview" OnRowCommand="EditGridData" runat="server" 
      AutoGenerateColumns="False" CellPadding="4" GridLines="None" AllowPaging="True" 
      OnPageIndexChanging="GrdState_PageIndexChanging" PageSize="20" EmptyDataText="Record is Not Available" 
      Width="93%"> 
      <Columns> 
       <asp:TemplateField HeaderText="Edit"> 
        <ItemTemplate> 
         <asp:LinkButton ID="BtnEdit" runat="server" CausesValidation="false" class="black skin_colour round_all" 
          CommandArgument='<%# Eval("Country_ID")%>' CommandName="Edit1" ForeColor="#6699FF" 
          Font-Underline="True"> <span>Edit</span></asp:LinkButton> 
        </ItemTemplate> 
       </asp:TemplateField> 
       <asp:TemplateField HeaderText="Delete"> 
        <ItemTemplate> 
         <asp:LinkButton ID="BtnDelete" OnClientClick="return confirm('Are you sure want to delete?');" 
          CausesValidation="false" class="black skin_colour round_all " CommandArgument='<%# Eval("Country_ID")%>' 
          CommandName="Delete1" runat="server" ForeColor="#6699FF" Font-Underline="True"><span>Delete</span></asp:LinkButton> 
        </ItemTemplate> 
       </asp:TemplateField> 
       <asp:TemplateField HeaderText="View"> 
        <ItemTemplate> 
         <asp:LinkButton ID="LBtnView" CausesValidation="false" class="black skin_colour round_all " 
          CommandArgument='<%# Eval("Country_ID")%>' CommandName="View1" runat="server" 
          ForeColor="#6699FF" Font-Underline="True"><span>View</span></asp:LinkButton> 
        </ItemTemplate> 
       </asp:TemplateField> 
       <asp:BoundField DataField="Country_Name" HeaderText="Country" /> 
       <asp:BoundField DataField="Description" Visible="false" HeaderText="Description" /> 
       <asp:TemplateField HeaderText="Description"> 
        <ItemTemplate> 
         <div class="DisplayDiv"> 
          <asp:Label ID="Label1" runat="server" CssClass="DisplayDesc" Text='<%# Eval("Description") %>'></asp:Label> 
         </div> 
        </ItemTemplate> 
       </asp:TemplateField> 

       <asp:BoundField DataField="CreationDate" HeaderText="Creation Date" DataFormatString="{0:dd/MM/yy}" /> 
      </Columns> 
     </asp:GridView> 
    </ContentTemplate> 
</asp:UpdatePanel> 

後面的代碼（如果你能看到我使用的命令名稱在網格視圖鏈接按鈕）：

public void EditGridData(object sender, GridViewCommandEventArgs e) 
    { 
     int i = Convert.ToInt32(e.CommandArgument); 
     Session["Country_ID"] = i; 

     if (e.CommandName == "Edit1") 
     { 
      SortedList sl = new SortedList(); 
      sl.Add("@mode", "GetRows1"); 
      sl.Add("@Country_ID", i); 
      SqlDataReader dr = emp.GetDataReaderSP("CountryMaster1", sl); 
      while (dr.Read()) 
      { 
       txtCountry.Text = dr["Country_Name"].ToString(); 
       txtDesc.Text = dr["Description"].ToString(); 
       ViewState["Country_Name"] = dr["Country_Name"].ToString(); 
       BtnSubmit.Visible = true; 
       BtnSubmit.Text = "Update"; 
      } 
     } 

     if (e.CommandName == "View1") 
     { 
      SortedList sl = new SortedList(); 
      sl.Add("@mode", "GetRows1"); 
      sl.Add("@Country_ID", i); 
      SqlDataReader dr = emp.GetDataReaderSP("CountryMaster1", sl); 
      while (dr.Read()) 
      { 
       txtCountry.Text = dr["Country_Name"].ToString(); 
       txtDesc.Text = dr["Description"].ToString(); 
       ViewState["Country_Name"] = dr["Country_Name"].ToString(); 

       BtnReset.Visible = true; 
       BtnSubmit.Visible = false; 
      } 
     } 


     if (e.CommandName == "Delete1") 
     { 
      SortedList sl = new SortedList(); 
      sl.Add("@mode", "DeleteData"); 
      sl.Add("@Country_ID", i); 

      emp.ExecuteNonQuerySP("CountryMaster1", sl); 
      Label1.Visible = true; 
      Label1.Text = "Record Deleted Successfully…"; 
      BindGrid(); 
     } 

    } 

希望這有助於。
