[Solved] Apply GridCalculatedColumn's Expression to its Footer

I have a grid that is programmatically created in Page_Load that also includes a varying number of calculated columns. Each column contains an aggregate (count, sum, etc.). However, one of my columns is a percentage that is calculated based on other bound columns. Each row's calculation is done perfectly, but the grid footer should apply the same expression to the rest of the footer's values. The real trick is that the expression being used by the grid is not known at design time so I am unable to manually create a custom aggregate.

Anyone have any ideas how I can use the expression and datafields from the GridCalculatedColumn to evaluate that column's footer?

The way of working is the next, when selecting a item from TaskRadGridView, we load data from the database:

Protected Sub TasksRGriVie_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)

Dim AuxTaskId As Integer

If TasksRGriVie.SelectedItems.Count > 0 Then

Dim item As GridDataItem = TasksRGriVie.SelectedItems(0)

AuxTaskId = CInt(item.GetDataKeyValue("taskID"))

LoadTaskDetails(AuxTaskId)

End If

End Sub

Sub LoadTaskDetails(ByVal selTaskID As Integer)

If TasksRGriVie.Items.Count > 0 Then

Dim auxQual As Integer = CInt(Me.SelQualHidFie.Value)

Dim curContractor As Integer = Session("CompanyID")

Dim objtask As OQCrewItem = listTask.Find(Function(c) c.taskID = selTaskID)

'Loads the list view with the current personnal

Dim ListPerAs As New List(Of OQCrewPersonnel)

'Getting data from the view state

If selTaskID > 0 Then

'listTask a property that gets data from viewState('listtask')

ListPerAs = listTask.Find(Function(c) c.taskID = selTaskID).personnel

PersonnelAssignedRTreLst.DataSource = ListPerAs.Where(Function(c) c.statusID = 1).OrderByDescending(Function(c) c.lastName).ToList()

End If

'Gets list of personnel

Dim listAvailablePer = OQProjectBL.GetAvailableCrewPersonnel()

Dim list = listAvailablePer.Where(Function(c) c.qualified = "Yes").OrderBy(Function(c1) c1.lastName).ToList()

PersonnelToAssignRGriVie.DataSource = list

PersonnelToAssignRGriVie.DataBind()

End If

End Sub

The when we select (highlight) a node from the RadTreeList PersonnelAssignedRTreLst, we get the data for PersonnelToAssignGriView, from the PersonnelToAssignGriView we can select (check) several items then when we click on the button PersonnelAddRBtn
on the header of this item we should add those items to PersonnelAssignedRTreLst, the problem occurs when the list of items related to the PersonnelToAssignGriView is like 500 rows, there is a problem when click on the PersonnelAddRBtn
Button from the header, it does not make a postback I get this error. Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. It doesn't make a postback, I search in the web, I'm not using Response.write anywhere. Thinking that the problem could be that the button is inside the radajaxpanel i set a button Add on the RadToolBar, but i get a similar error, it never goes to the function established on the serverside, i set a debugger on the JS function selBut that executes onClientButtonClicking event, then i got an exception on telerik code on line 6224 see that on image related.
There is another odd behavior of the page, in some computers there isn't any exception, could be a configuration that i'm missing?.

RadChart Month Name on XAxis

Hello there,

I am getting two columns from database (using SQL Data Source) namely points and month, I am summing the points based on month number for example a person gained 500 points in month 6 (which means June). The data appears in this format.

500, 6
1100, 7
900, 8
430 9

and so on...

Now I am binding the points (the first column) to y-axis of rad chart and month number to x-axis. But I want x-axis values to appear as month names instead of numeric values like June or Jun for 6, July or Jul for 7 and so on...

How can I convert xaxis numeric values to month names ?

Thanks.

How to ajaxify a multiview that contains a RadScheduler and GridView?

I have a MultiView control, and on View2 I have several LinkButtons, GridView, RadScheduler and RadListBox with check boxes on every item. I want to be able to update the whole View2 on RadScheduler_AppointmentUpdate event. How can I accomplish that? I've used RadAjaxManager and have set AjaxControlID="RadScheduler" . For AjaxUpdatedControl I've set View2 and got the error: "Controls added to a ViewCollection must be of type View"
On THIS thread you said that I should wrap the whole MultiView with a Panel. But after I do that, I'm not able to check any checkbox inside RadListBox. Edit: Checking RadListBox items is essential for populating appointments in RadScheduler.
Is it possible to refresh a MultiView's view on RadScheduler_AppointmentUpdate event?

ajaxify a GridTemplateColumn column

Hello,

I am pretty new to Rad controls, so please point me to articles that help explain this, but this is what I am trying to do.

I used a RadGrid control on my page, and included a GridTemplateColumn column in my grid by implementing the ITemplate interface. The template column is essentially a list of items in a drop down. This is working beautifully, but now I want the rest of the columns in the row to be updated accordingly when a user changes a value in the drop down of this Template column. I want to do this without doing a complete postback to the server.

Any help on how I can do this *correctly* would be greatly appreciated. I have been reading various articles and trying out things, but nothing is working too well.

Also, I don't know if this matters, but the data for my grid and the structure of the grid is completely created at run time without using any SqlDataSource controls.

Appreciate any input,
Thank you!

RadCalendar MultiViewRows="3"

I got this RadCalendar in my aspx page with three calendars stacked up vertically. I am binding some scheduling data to these three mini calendars and would like to limit the data to only the date’s show on the mini calendar. I wonder if there is a property of the RadCalendar that gives me the show date min and show date max. When user uses the fast navigation button to forward and backward the months, these properties should change accordingly. Do these properties exist? Thanks.

Body and Location Attributes

Hi

I'm new to using Telerik controls, so please be gentle.

I am working against Exchange which returns a body attribute in HTML and location in plain text. Could you please explain in simple terms how I can make these attributes available on insert and edit of an appointment?

Many thanks,
