When I install the "Telerik UI for ASP.NET AJAX R1 2018" I notice that there are xml files with the same names as the dll files that I have to add to my project's references.

What is the purpose of those xml files and how to use them?

filtering (blank) from columnfield

I'm tring to remove the "(blank)" value from my columns values .

the field "aircraft" has blank values and I want to ignore the blank column.

I've tried several things from code behind (working with vb.net) and nothing happens.

If I try filtering this field from the webpage, I get an error of :

"cannot convert object of type 'system.string' to type 'telerik.web.ui.pivotgrid.core.nullvalue'

<telerik:RadPivotGrid RenderMode="Lightweight" AllowPaging="true" PageSize="10" Height="500px"

ID="RadPivotGrid1" runat="server" allowfiltering="true" emptyvalue="0">

<Fields>

<telerik:PivotGridColumnField DataField="aircraft" showgroupwherenodata="false">

</telerik:PivotGridColumnField>

<telerik:PivotGridRowField DataField="Category" ZoneIndex="0">

AutoComplete

When looking at the FireFox Developer it doesnt seem the value from the browser autocomplete is filling in the values. Even though the screen shows the value in box, the inspector does not show any value. Where is this value? I need to capture that value on the client-side markup. If i select the address list from the browser prefill, it fills in the controls correctly. Referencing screen shots: I can see the "DG3123" in the inspector and the zip displays "59332", but the inspector shows the zip as "". So no value. If i click on the control, it received focus and fills in the zip value of "59332". Please advise how to workaround this issue. As stated, i need to capture this before moving to the next step in the wizard, as its making the validation value.

Please see my screen shots.

Thanks!

How to get message back from Update of ClientDataSource

I'm using the following ClientDataSource to bind a radgrid.

<telerik:RadClientDataSource runat="server" ID="clientDataSourceGrid">

<ClientEvents OnCommand="dataSourceCommand" OnRequestStart="requestStart" OnRequestEnd="requestEnd" />

<DataSource>

<WebServiceDataSourceSettings>

<Select Url="../../api/apd" RequestType="Get" />

<Insert Url="../../api/apd" RequestType="Post" />

<Update Url="../../api/apd" RequestType="Put" />

<Delete Url="../../api/apd" RequestType="Delete" />

</WebServiceDataSourceSettings>

</DataSource>

<Schema>

<Model ID="APDId">

<telerik:ClientDataSourceModelField FieldName="AM" DataType="String" />

The Web API action to do the update is as follows:

public void PutAPD(int id, APD apd)

{

// Do the update ....

// How can I return a message in case something goes wrong in the update?

}

My question is: how can I return a message from PutAPD back to the client? I want to be able to inform the user in case the update failed.
