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.

Hi ,

 

If you throw an error or return something invalid, most probably you will be able to use the OnRequestFailed event handler for this requirement:
https://docs.telerik.com/devtools/aspnet-ajax/controls/clientdatasource/client-side-programming/events/overview

I hope this will prove helpful.
