GridPanel的列是动态生成的，而且是可以进行的列编辑的。
而我把行上的其中一列，替换成ComboBox时，出现了错误。
错误信息：Error during ClientConfig initialization. StoreID
Ext.Net.ComboBox cmb = new Ext.Net.ComboBox(); if (!string.IsNullOrEmpty(strAllowBlank)) { cmb.AllowBlank = true; } if (!string.IsNullOrEmpty(strRegex)) { cmb.Regex = strRegex; } if (!string.IsNullOrEmpty(strMaxLength)) { cmb.MaxLength = Convert.ToInt32(strMaxLength); } if (!string.IsNullOrEmpty(strListeners)) { cmb.Listeners.Change.Handler = strListeners; } if (!string.IsNullOrEmpty(strEditable)) { cmb.Editable = false; } if (!string.IsNullOrEmpty(strStoreID)) { cmb.StoreID = strStoreID; } cmb.TypeAhead = true; cmb.ForceSelection = true; cmb.DisplayField = "ItemCode"; cmb.ValueField = "ItemName"; cmb.MinChars = 1; cmb.ListWidth = 400; cmb.PageSize = 10; cmb.ItemSelector = "tr.list-item"; StringBuilder sb = new StringBuilder(); sb.Append(" <tpl for=\".\"><tpl if=\"[xindex] == 1\">"); sb.Append("<table class=\"cbStates-list\" ><tr>"); sb.Append("<th style=\"color: #2f353b !important;\">物料编码</th>"); sb.Append(" <th style=\"color: #2f353b !important;\">物料名称</th>"); sb.Append("<th style=\"color: #2f353b !important;\">存货量</th>"); sb.Append("</tr> </tpl>"); sb.Append("<tr class=\"list-item\">"); sb.Append("<td style=\"padding:3px 0px;\">{ItemCode}</td>"); sb.Append("<td>{ItemName}</td>"); sb.Append("<td>{OnHand}</td>"); sb.Append("</tr> <tpl if=\"[xcount-xindex]==0\">"); sb.Append(" </table> </tpl> </tpl>"); cmb.Template.Html = sb.ToString(); col.Editor.Add(cmb); GridPanel.AddColumn(col);//到这一步的时候出现错误了。
请问这个问题有遇到的朋友没有？该如何解决啊？

这个是用代码创建combobox，可以多列显示，模糊查询，ajax获取数据。
直接添加到页面上就可以了。如：panel1.add(cmb);
加到gridpanel的编辑列中：
col.Editor.Add(cmb);——先加到编辑咧中
GridPanel.AddColumn(col);——然后再加到gridpanel的列中
