Using firecommand in combination with needdatasource/xpath

[I. Breukink]

I have a grid that uses a needdatasource in which a xmldatasource is connected and i have a separate query-box, which uses a firecommand to update the grid using the xpath settings in the datasource. I have used this method, because now i can create a more complicated xpath method for selecting. I works fine, expect when the result for the the xpath selection is zero (no records found). Then the firecommand is not working, i think because the mastertable is not existing then. However the datasource itself always contains all the records, so the mastertable doesn't have to be empty. When i reload the grid with all the records, it works fine again. How can i solve this?

Hi I. Breukink,

Indeed the fireCommand does not works as expected and the logic does not enter into the ItemCommand because you do not have any items into the RadGrid. In your case I suggest you to use ajax and perform ajax request. Then on the server you could call Rebind() method and bind the RadGrid to the filtered data.

Please give it try and let me know if you experience any problems.
