如何更改jqGrid中的特定RowData值？

和所使用的腳本是

<script type="text/javascript"> 

     var lastSelection; 
     var idCategoria; 
     var nomeCategoria; 

     function editRow(id) { 
      if (id && id !== lastSelection) { 
       var grid = jQuery("#<%= JQGrid1.ClientID %>"); 

       if (document.getElementById(lastSelection + "_NomeCategoria") != null) { 
        if (document.getElementById(lastSelection + "_NomeCategoria").value != undefined) { 
         var objeto = document.getElementById(lastSelection + "_NomeCategoria"); 
         idCategoria = objeto.value; 
         nomeCategoria = objeto[objeto.selectedIndex].text; 
        } 
       } 

       if (lastSelection != undefined) { 
        grid.updateGridRows("{IdCategoria:" + idCategoria + "}", lastSelection); 
        grid.saveRow(lastSelection, false); 
        //grid.setCell(lastSelection, "IdCategoria", idCategoria); 
        //grid.setRowData(lastSelection, "{IdCategoria:" + idCategoria + "}"); 
       } 

       try 
       { 
        grid.restoreRow(lastSelection, defineCategoria); 
       } 
       catch(err) 
       { 
        alert(err.description); 
       } 
       grid.editRow(id, true, selecionaCategoria); 
       lastSelection = id; 
      } 
     } 

     function selecionaCategoria(id) { 

      var grid = jQuery("#<%= JQGrid1.ClientID %>"); 
      var linha = grid.getRowData(id); 
      var idCategoria = linha.IdCategoria; 
      var comboCategorias = document.getElementById(id + "_NomeCategoria"); 
      if (idCategoria != "" && idCategoria != undefined) { 
       try { 
        for (var i = 0; i < comboCategorias.childNodes.length; i++) { 
         if (comboCategorias.childNodes[i].value == idCategoria) { 
          comboCategorias.childNodes[i].selected = true; 
          break; 
         } 
        } 
       } 
       catch (err) { 
        alert(err.description); 
       } 
      } 
     } 

     function defineCategoria(id) { 
      var grid = jQuery("#<%= JQGrid1.ClientID %>"); 
      grid.setCell(id, "NomeCategoria", DefineUrlCategoria(idCategoria, nomeCategoria)); 
     } 

     // The FormatFunction for CustomFormatter gets three parameters 
     // cellValue - the original value of the cell 
     // options - as set of options, e.g 
     // options.rowId - the primary key of the row 
     // options.colModel - colModel of the column 
     // rowData - array of cell data for the row, so you can access other cells in the row if needed 

     function DefineUrl(cellValue, options, rowObject) { 
      var caminho = ""; 
      if (isArray(rowObject)) { 
       if (rowObject[1] != "" && rowObject[1] != undefined) { 
        //var caminho = "<a href='/Ferramenta/Graficos/GraficoCategoria.aspx?idCategoria=" + rowObject[1] + "'>" + cellValue + "</a>"; 
        caminho = DefineUrlCategoria(rowObject[1], cellValue); 
       } 
       else { 
        caminho = cellValue; 
       } 
      } 
      else { 
       if (idCategoria != "0") { 
        caminho = DefineUrlCategoria(idCategoria, nomeCategoria); 
       } 
       else { 
        caminho = nomeCategoria; 
       } 
      } 
      return caminho; 
     } 

     function isArray(o) { 
      return (typeof (o.length) == "undefined") ? false : true; 
     } 


     function DefineUrlCategoria(idCategoria, nomeCategoria) { 
      var caminho = "<a href='/Ferramenta/Graficos/GraficoCategoria.aspx?idCategoria=" + idCategoria + "'>" + nomeCategoria + "</a>"; 

      return caminho; 
     } 
    </script>

當行不處於編輯模式時，第五列顯示鏈接，並在編輯時顯示下拉列表。要在下拉列表中選擇正確的項目，我使用具有來自數據庫的ID的第二列。

問題是，更改項目並將其保存到數據庫後，此列值不會更改。我怎麼能在grid.saveRow（lastSelection，false）之後做到這一點; ？

謝謝。

我找到了解決方案！

我改變下面

if (lastSelection != undefined) { 
    grid.updateGridRows("{IdCategoria:" + idCategoria + "}", lastSelection); 
    grid.saveRow(lastSelection, false); 
    //grid.setCell(lastSelection, "IdCategoria", idCategoria); 
    //grid.setRowData(lastSelection, "{IdCategoria:" + idCategoria + "}");

}

代碼向該

if (lastSelection != undefined) { 
    grid.setRowData(lastSelection, {IdCategoria:idCategoria}); 
    grid.saveRow(lastSelection, false);}

的問題是，我經過第二個參數爲字符串。
