子グリッドビューでの編集は、展開を崩壊

Question

私は親グリッドGVInvoiceDetを持っています。このグリッドのCRUD操作は正常に動作しています。親の各行に、私は子グリッドGVTaxDetailsを持っています。これは画像のクリックで開きます。すなわち、展開/折りたたみ機能です。

子グリッド内のCRUDも探しています。しかし、子の中でeditをクリックすると、編集のためのtexboxは表示されず、親グリッドが崩壊します。私は仕事がためのコードを投稿...行ってしまった

Answer 1

：ここ

はコード

protected void GVTaxDetails_RowEditing(object sender, GridViewEditEventArgs e) 
     { 
      GridView gvTemp = (GridView)sender; 
      gvUniqueID = gvTemp.UniqueID; 
      //gvEditIndex = e.NewEditIndex; 
      gvTemp.EditIndex = e.NewEditIndex; 
      GVInvoiceDet.DataBind();   
     } 

親行編集コード

protected void GVInvoiceDet_RowEditing(object sender, GridViewEditEventArgs e) 
     { 
      GVInvoiceDet.EditIndex = e.NewEditIndex; 
      GVInvoiceDet.DataBind(); 
      BindItemGrid();   
     } 

ASPXファイルをrowediting子グリッドです他の人が同様の状況に遭遇した場合。

親のrowdataboundにdivを開いたままにしてeditIndexを更新するコードが追加されました。

protected void GVInvoiceDet_RowDataBound(object sender, GridViewRowEventArgs e) { 
      GridViewRow row = e.Row; 
      if(row.RowType == DataControlRowType.Header) 
      { 
       return; 
      } 
      else if (row.RowType == DataControlRowType.DataRow) 
      { 
        //Find Child GridView control 
        GridView gvTax = new GridView(); 
        gvTax = (GridView)row.FindControl("GVTaxDetails"); 
        if (gvTax.UniqueID == gvUniqueID) 
        { 
         gvTax.EditIndex = gvEditIndex; 
         //Expand the Child grid 
         ClientScript.RegisterStartupScript(GetType(), "Expand", "<SCRIPT LANGUAGE='javascript'>expandcollapse('div" + ((DataRowView)e.Row.DataItem)["itemcd"].ToString() + "','one');</script>"); 
        } 
      } 
    } 

expandcollapseはASPX側の関数である：

function expandcollapse(obj, row) { 
      var div = document.getElementById(obj); 
      var img = document.getElementById('img' + obj); 

      if (div.style.display == "none") { 
       div.style.display = "block"; 
       if (row == 'alt') { 
        img.src = "Images/minus.png"; 
       } 
       else { 
        img.src = "Images/minus.png"; 
       } 
       img.alt = "Close View Taxes"; 
      } 
      else { 
       div.style.display = "none"; 
       if (row == 'alt') { 
        img.src = "Images/plus.png"; 
       } 
       else { 
        img.src = "Images/plus.png"; 
       } 
       img.alt = "Expand View Taxes"; 
      } 
     }
