这是我的观点。我在这里发布了我的视图，控制器和jsonHelper.cs供您参考。请仔细阅读。并附上了我的问题的屏幕截图。
先生，我已经粘贴了上面的所有代码。我想在下拉列表中找到“列名称”。我希望你能帮助我。??

答案 0 :(得分：0)
在jQgrid的colModel中，name和index属性使用您的C＃对象属性名称。我想它应该是ColumnName，不确定你是如何定义的。请相应更改
colModel: [
{ name: 'TableName', index: 'TableName', width: 40, align: 'left',
Style:'padding-left:15px;'},
{ name: 'ColumnName', index: 'ColumnName', width: 40, align: 'left',
width: 80, formatter: 'select', type:'select', edittype: 'select',
editoptions: { value: "1:One;2:Two" } }
]
答案 1 :(得分：0)
colModel: [
{ name: 'Table_Names', index: 'Table_Names', width: 40, align: 'left', Style:'padding-left:15px;'},
{ name: 'Column_Names', index: 'Column_Names', width: 40, align: 'left', width: 80, formatter: 'select', type:'select', edittype: 'select',
editoptions:{
dataUrl: '/Schema/GetGridData?DataSource=' + '@ViewData["ServerName"]' + '&InitialCatalog=' + '@ViewData["DataBaseName"]' + '&UserName=' + '@ViewData["UserName"]' + '&PassWord=' + '@ViewData["PassWord"]',
buildSelect: function (data) {
var response, s = '<select>', i;
response = jQuery.parseJSON(data);
if (response && response.length) {
$.each(response, function (i) {
s += '<option value="' + this.Column_Names + '">' + this.Column_Names+ '</option>';
});
}
return s + '</select>';
}
}}]
我认为现在你可以获得价值。如果你没有看到萤火虫 - ＆gt;控制台，json为您返回的内容。如果您想要
