Hello All,

I have simple radgrid with to/from date filter option. But when I change the dates in the filter, its not updating the grid. Following is my simple code. I have tried everything in the tutorial, but no luck. Any help is appreciated.

</telerik:GridBoundColumn>

</Columns>
</MasterTableView>
</telerik:RadGrid>

Hello Devang,

Please make sure that you are not using the DataBind() method to bind the grid. Performing complex grid operations such as Inserting, Deleting, Updating, Hierarchy relations, Grouping, Exporting, Paging, Sorting, Filtering, etc. require accommodating appropriate database operations. Therefore, we suggest you to avoid Simple Databinding and strongly recommend the use of more advanced databinding methods, which automatically handle the aforementioned functions:

Declarative DataSource (DataSourceID property)
Programmatic Data Binding (NeedDataSource event, + DetailTableDataBind for hierarchy). You should set the DataSource property ONLY within these event handlers.

Instead of using a template, you can achieve this requirement using a GridDateTimeColumn with the following built-in properties:

<telerik:GridDateTimeColumn ... EnableRangeFiltering="true" EnableTimeIndependentFiltering="true">

And if you want to access the generated controls in the code-behind, you can check the approach suggested in the following post:

I hope this will prove helpful.
