View 1 RepliesI 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 have an edit button at the end of each row, when clicked it brings up an editable form with that rows information in it. I am using event listeners to pass the information back to the main datagrid. The only think i don't understand is, how do you update the datafield values in the datagrid.I've tried a lot of different things, variations myDatagrid.nameField.text = "Person's Name"nameField[1].text = "Person's name"Anybody know how I can target the specific rows of the datagrid to edit the values in them?I have looked a little into data binding, but I can't figure out how to bind the form (in a seperate class) to the datagrid in the main mxml file.

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 want to get all values in one of the columns of a datagrid and put them in an array, to use it as a dataprovider of a combobox, is this possible?
I use an ArrayCollection as the dataprovider of the datagrid, it's filled from the database.
Context: 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?

View 2 RepliesI 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.

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.

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.

View 5 RepliesCan we change the width of the datagrid column dynamically by clicking on the border of the column in order to display the complete string which is too long to be displayed and needs to be scrolled ? If so, How ?
Also, how can we ensure that the column width changes dynamically based on the number of characters / length of string; since many a times the data is too long to be displayed. Can we set the column width to take the length of data into consideration before displaying onto the datagrid ?
