Getting back the modifications made on the client

[Marc SOLDAT]

Hello,

If I try an sample of the treegrid for example, I can on the client make several operations such as create a row, move it, change values, and so on.

But is it possible to "submit" theses changes made on the cclient by a submit button or anything else, and getting the new data on the server side ?

Thanks in advance for your answer.

An example would be greatly appreciated.

Hi Marc, 

By using PageMethods, we can get the updated record details in the server side. For this we need to enable EnablePageMethods property in script manager. In the provided sample, we pass the updated records to the server side on button click action. Please find the below code example. 

 

 

[aspx.cs] 

[WebMethod] 

public static void getUpdatedRecords(List<object> record) 

{ 

    //get updated records 

} 

[aspx] 

<input type="button" onclick="getUpdatedRecords()" value="Updated Records" /> 

<asp:ScriptManager ID="ScriptManager" runat="server" EnablePageMethods="True" /> 

<script type="text/javascript"> 

    function getUpdatedRecords() { 

         var obj = $('#TreeGridControlDefault').ejTreeGrid('instance'); 

         var items = []; 

         for (var i = 0; i < obj.model.updatedRecords.length; i++) { 

             items.push(obj.model.updatedRecords[i].item) 

         } 

         PageMethods.getUpdatedRecords(items); 

    } 

</script> 

 

Please find the below sample link.
