How to get message back from Update of ClientDataSource

[Giorgos]

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 Giorgos,

 

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.
