View 2 RepliesContext: I have a data grid where the following has been implemented. tabbing through each column in a single row and creating a new row when tabbing from the last column. The last column in my datagrid is now a checkbox. I set the 'editable' to false as shown below (since we don't want editable text to be shown when user clicks on/tabs to checkbox.
Problem: When I tab through the columns of a given row, I cannot tab to the checkbox column and therefore cannot use the space bar to toggle between checked/unchecked. The user is forced to use the mouse to toggle the check box. Question: How do I let user tab to the checkbox column, and press spacebar to toggle between checked and unchecked?
I wanted to put a checkbox in one of the column of the datagrid. I tried using the cell renderer and could get a column with check box. But the problem is I want the datagrid for touchscreen and it should have multi selection enabled. As I select one check box the previously check box gets cleared. Pressing down the ctrl key do the job but in touchScreen that cannot be done. I read some posts in google where it was said that generating false CTRL press event. I have attached the cellrenderer for the checkbox that I have used.

I have a Flex 4, mx:DataGrid with the following (pertinent) properties set:
width="100%"horizontalScrollPolicy="off"
I have the minWidth set on all of the DataGridColumns and the width set on one of them. If I simply maximize/minimize the display (in browser or stand-alone flash player) of the application, the columns scale up and down nicely. But if you grab the edge of the application and drag it to make it bigger, only one column grows really big. When you drag the size down again, the one column remains big, but all of the other columns get squished way down.
I am using datagrid and added 3 columns to it in flex project. Data is provided to each column by using itemrenderer. Itemrenderer is checkbox for each column. Name of columns are col1,col2,col3. I want to make the checkbox in col1 selected when i selects the checkbox in col2. But i am not able to do this.

In my flex app I store the widths and visiblility of columns in an xml file. When the app loads it reads from the xml file and sets he columns values as applicable:
for(i = 0; i < columnsOrder.length; i++){
newOrder[i] = myDG.columns[Number(columnsOrder[i]) - 1];
newOrder[i].visible = (Number(columnsVisiblity[i]) == 1);

In a flex datagrid, by default clicking on column headers does sorting. I want it such that if a user clicks a column header the entire column is selected. I have the datagrid listening for the HEADER_RELEASE event so I know when the column header is clicked.
How can I have the column and header appear highlighted similar to how a row is highlighted when selected?

I am stuck in a problem working on Flex datagrid, in an AIR application. How can I access a specific row in datagrid in Flex. I am not talking about the selectedItem or any particular record of dataProvider of datagrid. What exactly I want to do is I am showing some files data (name, description etc.) on a datagrid, and the data of these files comes from an array which is the dataProvider of the datagrid. Now when these files are being uploaded one by one to the server (using a webservice), I want to show a ProgressBar on, say, "Progress" column in the datagrid. How can I access this column for a particular row in datagrid i.e. current file being uploaded.

[URL]I have a checkbox renderer i am placing into my Datagrid. The checkbox needs to do a sql query on the sqllite database and see if the show is marked as watched, if it is then make the checkbox as checked and if not mark the checkbox and not checked.
What i would like to do further to this is add the watched items to one XMLList and add the not watched episodes to a different XMLList and have the checkbox on click= move from one to the other list as per watched or not.

View 2 RepliesI have a column in a data grid that has the values of "Monday", "Tuesday" etc, as varchars, and I wanted to know, how do i sort the column to be in the correct order. Doing a normal sort doesnt work obviously, as the days are not alphabetically ordered naturally (Wed after Thurs). I am assuming some sort of itemrenderer, but anyone got a snippet of code to illustrate how this would work?
View 1 RepliesIn flex, I have a datagrid with 22 columns. I initially display all the columns. The width of each column right is uniform. Now when i change the visiblity of a few columns, the width of each column varies. How do i maintain a uniform column width for each column whether or not there are any invisible columns? how do i get the count of number of visible columns. the ColumnCount property returns total number of columns and not the number of visible ones.

View 2 RepliesI have a datagrid with three columns.In one column I have to add all the values and display the total value.
View 1 RepliesIn the below example I has called the OptimizeDataGrid method on Button Click event to resize the Column according to the data. whereas on the First Time of the Button Click event It called the function whereas the Datagrdi Column width alone is not set properly.whereas on second time it is working properly.For Eg : In the below statement the text value is coming as 55 and widthPadding is comes as 25. but the sum of these two value is not in the dg.columns[col].width.
dg.columns[col].width = text + widthPadding;
But the same is working on the second time of the Button click event.
