Can any one please let me know how to render the radio buttons in a grid,
i am facing trouble in that.

currently my code has a column with radio buttons and on load the default value of the grid should be selected. but the select is not happening.
i have used the radio button image instead of the radio button, since ExtJs does;nt support the radio button in the grid.

also it would be great if you guys can post link or sample code.

thanks in advance
