I'm using Visual Studio 2005 with the latest Telerik RadGrid component. We have disabled the AutoPostBack on the filter field and used JavaScript to intercept and stop the filter call made by the filter menu click. However we can find no way to then have a button on the page that then simulates the same call. Our attempts just won't work because the postback loses the filter details and when interrogating the grid filter values in the code-behind the select filter item is 'No Filter'.
Scenario:
1. Enter various filter values in columns and select the filter type from menu.
2. Click button that's posts back this detail and allows us to construct SQL to query on all column values.
We have tried a variety of options none of which seems to work (in VS2005 at least), can anyone point us in the right direction? Preferably with a detailed code example? You're help would be greatly appreciated!

Hi Cranialstrain,
To simulate a filter command fired from the button, you can take two approaches:
1. Attach an event handler to the client click event of the button, find the client object of the grid, get a reference to the master table view ($finid('<%=RadGrid1.ClientID%>').get_masterTableView()) and use the latter's filter method to trigger the filter command as described in the following help article:
http://www.telerik.com/help/aspnet-ajax/grid_filter.html
2. Another approach is to attach a server handler to the button's click event, and handle the filtering on the server by using the MasterTableView's FilterExpression property or the FireCommand method that is supported by each item in the grid:
http://www.telerik.com/help/aspnet-ajax/grdfirecommandeventfromcode.html
If you need the filter value and the filter functions used by the filtering to appear in the filtering row - just update the corresponding column's CurrentFilterValue and CurrentFilterFunction properties accordingly.
I hope this information helps.
