Hi Abhijeet,

Thanks for using Syncfusion products.

Before proceeding we need the below details of the controls that you have used in your application.

1.       You have mentioned in the query as “any controls”, whether you have mentioned Syncfusion controls alone or any other controls.

2.       If you are using Syncfusion controls then share us the details of the controls in which the values get vanished after every post back.

For now we have checked the Grid control (with main features like Grouping, Sorting, Paging and Selection) and Tools controls with server side post back. Its working fine for us.

Please let us know if you have any queries.

Hello, when i do a postback on selecting a row in the grid control, I lose the data on the grid.

Do I have to bind the data to the control on every page_load?
Doesn't the grid control keep the data if its a postback?

normally what i would do on the page_load event, i put the following


So the first time the page loads the grid loads the data fine, but when i select a row on the server side, on the postback the grid is empty, but i can grab the info from selected row on the selected row event.

How do I set up the controls to maintain their data and state?

Hi Gabriel, 

Thanks for the update. 

We have achieved your requirement by setting the DataSourceCachingMode property as View state in the ejGrid and created a sample for your convenience. Please refer to the code example and sample, 

Code example: 
<ej:Grid ID="Grid1"    AllowPaging="True" 
            EnableRowHover="true"     AllowCellMerging="false"  
             AllowReordering="false" Locale="en-US" AllowMultiSorting="false"  
              AllowSelection="True" Selectiontype="Single"  OnServerRowSelected="DefaultEvents_OnServerRowSelected"  
             . . . . . . .
