Export to excel not exporting anything when choosing more than 4 choices in combo box

[nzsr]

I have a grid that will bind upon choosing date with RadDatePicker and code in RadComboBox.
I have set the combo box like this:

<telerik:RadComboBox DropDownAutoWidth="Enabled" ID="cboCode" runat="server" AutoPostBack="true" CheckBoxes="true" EnableCheckAllItemsCheckBox="true"></telerik:RadComboBox>

 

When I choose more that 4 options, click the Search button, the grid shows the searched data but when i click the export to excel button, it exported nothing.

Meanwhile, if I choose less than 4 options, the data did get exported in the excel - please refer image attached.

 

Below is the code for export setting:

<ExportSettings ExportOnlyData="true" Excel-Format="Biff" IgnorePaging="true" ></ExportSettings>

<MasterTableView AllowMultiColumnSorting="true" DataKeyNames="some column name here" AllowNaturalSort="true" CommandItemDisplay="Top" UseAllDataFields="true">

Hi,

Such behavior usually occurs due the Data Binding. 

I advise that you use either the Declarative or Programmatic data binding technique and if already used, ensure that DataBind() method is not being called anywhere in the code behind. Check out the following article for more information: How to bind RadGrid properly on server-side

Additionally, you could share the markup and code behind for the Grid so that we can see how the Filtering/Exporting is handled for the Grid. 

Kind regards,
