As you change each column, the DG will try to adjust other columns so that they all fit on screen. Setting horizontalScrollPolicy="on" is one way to prevent auto-resizing. Another is to generate new DGColumns from the old ones, adjust the their widths and then set the .columns property once.
From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Manu Dhanda Sent: Monday, September 01, 2008 7:24 AM To: [email protected] Subject: [flexcoders] DataGrid columnWidth at runtime Hii, Can anyone help me to get a solution for the above written problem. I have a datagrid with 8 columns. And I want to increase it's column width on the mouse click of that cell (and decrease the other column widths in the same proportion). First column I want to keep constant (of width 20). Rest I want to change. Here is what I am doing: public function cellResizer(e:ResizerEvent):void{ var _cellIndex:Number = e.myCellIndex; for (var i:uint=1; i< this.columnCount; i++) { if(i == _cellIndex || i == 0) continue; if (i != _cellIndex) { this.columns[i].width = this.columns[i].width - 50; } } this.columns[_cellIndex].width = this.columns[_cellIndex].width + 300; } Now, as in the above function, I am getting the current cell and when I click it, I got the cellwidth increased as well. But, then after that, rest of the clicks will go totally uncontrolled, with varying widths. Anyone, who can guide me in a right direction please. Thanks, Manu. -- View this message in context: http://www.nabble.com/DataGrid-columnWidth-at-runtime-tp19255573p19255573.html Sent from the FlexCoders mailing list archive at Nabble.com.
