Flex :: Display Images From Sqlite Into Datagrid?

Jun 12, 2011

I have a number of thumbnail images (8K ish in length), stored in a sqlite database, encoded as base64 strings.

I would like to retrieve these images and present them into a datagrid (along with some other information from the DB)

The retrieval of information from the database works, but I cannot quite "see" how to connect the decoded result from the database to the datagrid, to display the images.

Below is some code, where I show (to simplify things) a simply DGrid and want to use the dataprovider to point to the select from the DB[code]...

Flex :: Datagrid Selects The Wrong Custom Cell In Datagrid

Mar 15, 2010

I am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:

If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

package components
{
import mx.containers.HBox;
import mx.controls.CheckBox;

Actionscript 3 :: Flex - Selection In Flex Datagrid Does Not Pass The ValueObject To SelectionChangeHandler Function

Aug 11, 2011

I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:

1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.

A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

Flex :: Represent HTML Table Structure In Flex DataGrid Or AdvancedDataGrid?

Feb 12, 2012

I'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.

Flex :: Pass An Edited Flex Datagrid To A CFC To Insert To A Database?

I have a datagrid which is editable and I need to send that back to the database via a CFC for insertion into the database after all the editing is complete. Dumping the array collection to cfdump tells me that I have an array with items and a structure but i cannot understand how to "loop" through each and insert into the DB.There seems to be very little written which actually works! My MXML and CFC are below but give me the error of "You have attempted to dereference a scalar variable of type class coldfusion.runtime.Array as a structure with members." -which is nice

Flex :: Datagrid - Flex AdavcedDatagrid Sorting Is Case-sensitive

Jul 27, 2010

I have several datagrids with changing columns. For the text fields the datagrid's sort function neems to be making a case sensitive compare. eg. the following list sorted would look like this apples strawberries Autos Autos should be with apples but since the capital A is counted differently all capital letters come after. I've found a lot of information on setting a CASEINSENSITIVE flag, but I can't figure out where to do this. The best solution would be one where I can override the default behavior to be case insensitive for all my datagrids and all my compare functions.

Flex :: Adobe Flex - Doing Group By At Client End (DataGrid To Pie Chart)?

Dec 23, 2010

I am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)

Company Model Year No
GM Chevy 2010 10
GM Chevy 2009 5
GM Pontiac 2010 12
Honda Civic 2009 12

and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).

I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?

Flex :: Improve Datagrid Performance When Using Itemrenderer With In Datagrid?

Jul 31, 2009

For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

Flex :: Assign DataGrid To Other DataGrid In Flex

May 13, 2011

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.

Flex :: Print Flex Spark Datagrid By Using The Mx PrintDataGrid?

Oct 4, 2011

Flex 4.5+ is I guess everyone is working on nowadays so I asked this question since I haven't yet find working both spark datagrid and the mx printdatagrid components together.
What I'm trying to achieve is to print all the data inside my spark datagrid. So when I do my research, we use the PrintJob or the FlexPrintJob classes.It works fine but when I need to print multiple pages since the data on my spark datagrid is quite long, I can't somehow find a way how to do it.The print output is only upto where the height of my spark datagrid.So in my research, they somehow managed it to use the mx:PrintDataGrid component.But sad to say, they did it with an mx:DataGrid also.how to use the mx:PrintDataGrid along with s:DataGrid.

var printJob:PrintJob = new PrintJob();
if (printJob.start())
{[code]....

If converting a spark datagrid columns to the mx datagrid columns is not possible, is there a way that I can print all the data on the spark datagrid using multiple pages?

Flex - Add Row To Flex DataGrid Without Changing DataProvider

I am creating the standard "Click to add row" control but I really don't want to dirty the dataProvider with a "placeholder" since it is bound to the model and could end up in the database. Is there a way to add a row that isn't represented in the dataProvider? I started down the road of adding an item directly to listItems but then that needed an item in rowInfo and then that need a reference in rowMap.
