Question

我使用codeplex mvc.grid，我希望在选择所有下拉列表后绑定网格

我的问题很简单：

我是mvc开发的新手，我有4个dropbox，每个dropdown触发下一个dpdown对象来绑定值。

如何使用ajaxform绑定网格。

如果我想选择第一个下拉列表，此操作会填充第二个下拉列表，此操作会填充下一个下拉列表...

最后，当我点击LoadListToGrid按钮时，我不想要REFRESH页面，只需绑定gridview即可。为什么我不能在mvc中这样做，我怎么能这样做，请告诉我

感谢您的帮助

1)create new partial view which will only render grid i.e
_grid.cshtml
//this is partial view
 @Html.Grid(Model).Columns(columns =>
  {
     columns.Add(c => c.customer_reference).Titled("Çek No").SetWidth(30);
     columns.Add(c => c.unvan).Titled("Ünvan").SetWidth(30);
     columns.Add(c => c.vergi_no).Titled("Vergi No").SetWidth(30);
     columns.Add(c => c.islem_tarihi).Titled("İşlem Tarihi").SetWidth(30).Format("{0:dd/MM/yyyy}");
     columns.Add(c => c.currency).Titled("Para Birimi").SetWidth(30);
     columns.Add(c => c.full_curr_amount).Titled("Tutar").SetWidth(30).Format("{0:C}").Css("align-right");
  }).WithPaging(10) } // ajax end
//partial view end

create method in controller to return that partial view i.e.
public actionResult _grid(pass dropdown values here)

2)In your main view...
<div id='gridTable'></div>
<input type="button" name="CheckList" value="LoadListToGrid" class="btn btn-default" id="loadgrid" /> 
$('#loadgrid').onclick(function(){ 
//write ajax call here and specify url as  url:'/controllername/_grid'

//in success function write this
success:function(data)
{
$('#gridTable').html(data);
}
});

follow this stape
1)create seperate partial view for grid
2)in ajax call pass dropdown value to partial view and add return html to any Div tag
