DevExpress GridView ExportToPdf doesn't export filtered data MVC

Question

I have a webpage with gridview from Devexpress and i've implemented export to pdf. But somehow I don't get the current filter, order or group setting. I'm wondering if there is something wrong with how i set my setting in code or something since I've googled a lot at seems like those options should be handled automatically in ExportToPdf as long as you have rigth setting. My _GripPartial.cshtml:

@Html.DevExpress().GridView(TreeMenuTest.Controllers.LogViewController.GridViewSettings).Bind(TreeMenuTest.Controllers.LogViewController.DataSource).GetHtml()

_LogView.cshtml:

    @using (Html.BeginForm("ExportToPDF", "LogView", FormMethod.Post))
{
 <div id="buttonExport" class ="gridBtn">
             <input type="submit" id ="ExportBtn" value="Export to pdf"  />
</div>}
<div id="buttonReset" class ="gridBtn">
             <input type="button" id ="ResetBtn" value="Reset Grid" onclick="javascript: ResetGrid()"/>
</div>
@Html.Action("Grid","LogView")

And finally LogViewController:

Any clues?

Ps. Asking me why I don't write to DevExpress support is not helpful, so please just don't comment at all.

Answer 1

Check the How to export GridView rows and keep end-user modifications (such as sorting, grouping, filtering, selection) KB Article and make sure if all the steps are implemented.

Answer 2

After help for @Mikhail i fix the issue by putting @Html.Action("Grid","LogView") in the Html.BeginForm in _Log.View.cshtml like that:

<div id="buttonReset" class ="gridBtn">
             <input type="button" id ="ResetBtn" value="Reset Grid" onclick="javascript: ResetGrid()"/>
</div>
@using (Html.BeginForm("ExportToPDF", "LogView", FormMethod.Post))
{
 <div id="buttonExport" class ="gridBtn">
             <input type="submit" id ="ExportBtn" value="Export to pdf"  />
</div>

@Html.Action("Grid","LogView")}
