VS 2008 Charts - Unbinding / Rebinding Data
Apr 14, 2010
The chart on my project is populated click of a button using Chart1.DataSource = The data the chart displays depends on the selection made from a series of drop down lists before the button is clicked. I need to be able to create the chart, then be able to change the selections of the drop down lists and click the button again to show the new data but I am getting the error "A chart element with the name 'element name' already exists in the 'SeriesCollection'" Do I need to "unbind" the data/series before re-binding and resetting the properties of the chart each time the button is pressed?

I am able to dynamily bind my grid to the cube based off the facillity I have selected. Now, if a facility has multiple cubes, I want the users to switch between the two cubes dynamicly, so I have created a drop down list showing their cubes and the ones that they can select. Currently I'm been trying several things in order to "rebind" the data but they don't seem to be working, so I figured I would attach my code to see if anyone Had a good idea.
If I make the cube change then switch back over to change facility and then back to the page, the new cube will load. So I have to find a way to do it in the one step rather then have them navigate to another page and then back again. Perhaps auto navigate them to a page and have that page send them back etc... Anyway here is the code: I first bind the data via the page_prerender call
[Code]....
Then the code drops down into the LoadCube(FacilityID) sub routine
[Code]....
Then here is the setup for the subroutine that will call the page load/ should change the cube to the correct cube.
[Code]....

I have a GridView and Formview attached to the same ObjectDataSource.
Everything is working ok so far.
If I enter new search criteria and click "Search", both the GridView and FormView rebind properly to the ObjectDataSource results. And I am able to page through the FormView records and they match the GridView records above.
When I click a sort link in the GridView, the ObjectDataSource returns the correct results based on the header link's commandName of 'Sort' and the CommandArg of 'SortExpression'.
The only thing wrong now is on the sort, the formview records do not reflect the reversing of the sorted record order. If I page through the FormView the records remain in the same order.
Why does the FormView not recognize the ObjectDataSource's changed results on the sort post back (even if it is only the sortExpression parameter of my ODS select method).
How do I get the FormView to rebind to the new ODS result set? I have called formview.DataBind() from every event I can think of. That does not seem to work either.

I have a text box in a FormView that I use to display the return value from the stored procedure that I'm using to maintain the data. For assorted reasons, I'm not able to use the built in ability of the FormView to manipulate the data.
I have the following code at the end of the procedure that calls the stored procedure. It is a snippet that omits the bulk of the procedure.
[Code]....
As is, the label text is updated with the message. However, when I uncomment out the code that manipulates the SQL Data Source and rebinds the FormView, the label text is NOT updated. I can't figure out why it craps out.
1) AdvisoryMessageText is declared at the class level for the code behind, so it should be retaining the value across all of the procedures as their caloled.
2) TextBoxAdvisoryMessage is contained within the FormView EditTemplate.

I am working with a formview edititemtemplate. Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values. These dropdown values get binded during page load. I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.
I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback. I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render. I'm just not sure how to get the stars aligned here. The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender. However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.

I created a GridView that uses a custom paging method that allows for alphabetical paging. I seem to be having some problems now rebinding the GridView after a delete occurs. The row is deleted, it's just that the rebinding doesn't happen so to the user it looks like the delete failed. Been over and over my code and can't understand why. See the final block which is supposed to fire on the GridView1_ItemDeleted event.

Question: Anybody has experience with ZedGraph / MS-Chart controls ?
I am thinking about which to use ?
Basically, I have a tendency to ZedGraph, because I need .NET framework 2.0 while MS-Chart is 3.5 (and I don't know how well a 3.5 assembly works on 2.0) and because I could use it privately, too (I use Linux privately).
But I don't know if MS-Charts offers more. Does ZedGraph for example offer reasonable quality 3d piecharts ?
And reasonable color design, like gradient colors ? And if it does, is it as simple (or nearly as simple) as MS-Chart controls ? And does ZedGraph offer databinding, e.g. a datatable from a database ?
