Hi :

I want to expand or collapse grid in javascript.

I don't want to use the "Initial Hidden Grid" property to do this.

Because i will expand or collapse grid depends on the records is zero or not.

If the records is 0 => collapse grid, else expand it.

But i can't find a method to do it.

Any body can help me?

Thanks.

Hello,

It is again the common problem - which is the first the egg or the chicken?

- Also in order to check if you have records - the grid is already construct (expanded), since of the ajax call (we do not know initially how many records we have).

- If you make the grid initially hidden it is quite possible, that you have records in the view

and so on.

I think that there are two possible solutions:

1. Before to open the grid check if the current query has records. (The most clear way)

If this is the case construct the grid with hiddengrid:false otherwise hiddengrid:true

2. Use loadComplete event to check if you have records and then either use setGridState (currently this method is only in GitHub)

or trigger the click to hide/show grid button.

Hi Tony :

Thanks your great help.

I use the following method to do it.

$(".HeaderButton", $('#mygrid')[0].grid.cDiv).trigger("click");
