Check All and Uncheck All

[Keith Hubert]

Hi All,

I'm sure this has been asked before but searching I cant find it.

I would like to put a button on a grid to allow the user to either select All check boxes or Un-select All, which would be only those that are checked.

The grid displayed is filtered to that user.

Please point me in the right direction.

Hi Keith,
I don't have Version 10 any more so I don't know if this is the same but in V11 by default there is a check box in the header that does exactly that click on it and it checks all the rows and click it again and it un-selects all the rows, Unless you are wanting something more complex. But if not this is great, no code already built in, Hell I love Alpha Five!

Hi Bruce,

Thanks for your input. This might work in V10 if you can tell me how you got the checkbox you highlighted.

When you say by default, is this a grid or a dialog?

The has select checkbox property has a second option - see attached

Hi David,

Thanks for that, is this connected to the logical field I have in the table? If yes how?

Re: Check All and Uncheck All

hello

all i did was check the selection "has checkbox property and select "multiple pages" property. the checkbox on the label bar appears automatically. clicking it either selects or clears the entire row of records.

which would be only those that are checked.

if you have selected few records and want to clear them you may have to click the button twice. one to select all and the second one to clear the list.
wish there is a method similar to {grid.object}.fliterCheckedRows to clear the the selected rows, then you can just add a button and use that method to clear the rows selected.

Ah, No it is a Grid system field so maybe we are talking at cross purposes. Here is what i am talking about. there are a bunch of videos in the V10 video section.

Hi Bruce,

Thanks for pointing me to the videos. These show how to create a filter, that is not what I'm trying to do.

I need to set a user_id value to each of the rows checked.

Keith,

There are some good ideas from Bob Moore in the following post

http://msgboard.alphasoftware.com/al...elete+checkbox

I have tried a quick test. Put the following in Column Properties, Column Heading

Select<br><input type ="checkbox" id="d1" onclick="d_flag = $('d1').checked?true:false;for (i=1;i<={Grid.object}._rowsInGrid;i++){{grid.Object}._setValue('G','Mycheckboxcolumn',i,d_flag);}">

Substitute Mycheckboxcolumn for your field name and you will probably need tp centre the cell contents for things to line up.

Hi David,

Many thanks for this. The code works just how I want. I could never have worked this out to get this result. Another notch in the learning tree.

How do I centre the cell contents?

Re: Check All and Uncheck All

Hi,

Glad it's what you were looking for.

To centre the checkbox in the row use Cell in-line style

text-align: center; + you may need to fix the width of the column header and the cell

Hi David,

I'm having a slow day today, I cant see Cell in-line Style.

I have CheckBox Properties but can't see how to make the check box centre with the Style Editor.

Re: Check All and Uncheck All

Maybe you have something different in your grid.
