Date Sort in a DataGrid – the easy way

Posted on by — No Comments ↓

While trying to give suggestions to a post on the Flex Forum, I modified my Simple Data Grid to include a column for a Date. The poster had an issue with sorting the column with dates in it. My guess is, the Date value is actually a String object. It really isn’t very hard to create a Date from a string, just parse out the String and feed the appropriate date times into the Date object. Here is how I create the random date value. Since I insert the value into the item Object as a Date object, the sort Continue reading Date Sort in a DataGrid – the easy way→

Stacked Column Chart with Line Series

Posted on by — No Comments ↓

On the Flex Forum, I was attempting to help someone find their issue to a Stacked Column Chart with a Line Series. The y-axes values were not corresponding with the data being provided. This seemed like a glitch and I even attempted a work around by finding the minimum and maximum values. Finally, after looking at the Stacking Columns example and the Multiple Axis Example, reconstructed the chart using the static objects instead of dynamically creating the chart. From there, I recreated the chart items in a function and determined that the first issue the poster was having was building Continue reading Stacked Column Chart with Line Series→

Simple DataGrid with Row Background Update

Posted on by — No Comments ↓

On the Adobe Flex forum, a question was asked about changing the background color for a row to a different color if the user selected it and hit the DELETE key. So, I updated the Simple Data Grid to include this feature. It doesn’t delete the row, but changes the background color to grey. The first step is to capture the keyboard action. To do this, a listener has to be created and set to listen for a KeyBoard event. I set it for the stage, but doing so requires that the function is called when applicationComplete instead of earlier.

Simple Chart Overlay

Posted on by — No Comments ↓

One of the screens I created for work is a “dashboard” type that allows the view to quickly see the current status of service call volume.   There are multiple charts on the display, but one of them is a column chart that shows the current day’s numbers vs. the prior week of the same day.  By having this information, the viewer can see if the volume of calls is in a “normal” range, because the it fluctuates throughout the day and the week, but is similar based on the day of the week.  Friday’s call volume is usually lower than Continue reading Simple Chart Overlay→

Update to Egg Timer

Posted on by — No Comments ↓

On one of my projects at work I ended up using two Egg Timers but in different states. Since it would be easier to know if the correct Egg Timer was in the correct state, I added a couple of new parameters to the Egg Timer. Then I replaced the static colors with these defined variables to make it work. After those simple changes, the Egg Timer parameters can easily be added when placing the component. Fairly simple. Since the color parameters are already set as uint, there is no for any further conversion to make the color. I also Continue reading Update to Egg Timer→

Simple DataGrid with ArrayCollection Update Example

Posted on by — No Comments ↓

I was helping out on the Flex community forum and one of the posts needed a little more of example than I could give using the forum post tools. So, I decided to create a quick example of a DataGrid using an ArrayCollection for the dataprovider. The ArrayCollection is created dynamically using a randomization selection from two static arrays. Then there is an option for updating the list showing which of the items have “Red” as the color value. I also put a couple of other items in the example, including an ItemRenderer for the DataGrid and a button holder Continue reading Simple DataGrid with ArrayCollection Update Example→
