Good Day gep13

I have a Situation , i thought one of my Controls does not have a property Autopostback set to true, i checked them. Am using infragisitc controls and i have a grid, and on textchanged event am calling the Function to bind the grid and it bring data but the Grid remain with no data until i click something else that is not related to the grid and the data shows. i have set Autopostback property from the textbox that is in a usercontrol but still it persist.

Thanks
