Hi,

My RadGrid has three layers of nested grids. I'm using EditForms with templates throughout.
I want not more than one edit/insert form being shown in the whole grid at the same time. How can I achieve that?

I tried several ways, but the behaviour is never really how I want it. E.g. when the insert form is displayed in the the MasterTableView, it will stay open no matter which insert/edit button I click.

If an edit form is displayed in the MasterTableView, and I click any other insert or edit button, the form is not shown, but nonetheless the Item stays in edit mode.
Maybe I need to rebind the Grid at some point?

Does anybody know the best practise?

Thank for your help,
Jens

Drag Grid Row to a Dynamically-Created Dock Control

Hi, all.

I have a question regarding the RadGrid, RadDock and Javascript. I have a page that creates dynamic docks upon the user's request. The docks the users select will have their own separate .ascx controls loaded into them. One of these is a RadGrid and the other is the RadScheduler (both may or may not be loaded, depending on the user's configuration). I've seen the demo where a grid row is dragged to the scheduler, but I'm having some trouble replicating it since I can't use '<%= FindControl("schedCtrl").ClientID %>'; the page errors out since that control doesn't exist on the .aspx page at first. I've also tried to use eventArgs.get_destinationHtmlElement, but that only gives me the rendered div tag and not the actual control ID.

Is there something that I've missed or is there another way to get to the control's ClientID inside of another dynamic control?

[Solved] Copying an Excel range of cells into a RadEditor and reading that range into an XDocument

I have a very tricky task that I must perform. What I need to be able to do is allow a user to Past a section of Excel cells into a radeditor then on the C# side read those cells into an XMLDocument. I see that the radeditor has a HTML content view and I was hoping that I could read the html, parse it after reading it into xml format. If this is possible could you give me some guidance as to the best way to do this. I know that this is non-standard but any help would be great!!!!

Thanks,

grid not grouping data - says grouping field not found in the source table

Hi

I am using quite an old version of radgrid (q3 2009). The grid is not grouping my data. I have tried to group the data programmatically and declaratively and i get the same error. I am trying to group the data by a field called Reg which definitely exists in the underlying data as it displays fine in the grid if i remove any attempt to group the data

Here is the code

Dim expression As GridGroupByExpression = New GridGroupByExpression

Dim gridGroupByField As GridGroupByField = New GridGroupByField

'SelectFields values (appear in header)

gridGroupByField = New GridGroupByField

gridGroupByField.FieldName = "Reg"

gridGroupByField.HeaderText = "Reg"

expression.SelectFields.Add(gridGroupByField)

expression.GroupByFields.Add(gridGroupByField)

gridJourneys.MasterTableView.GroupByExpressions.Add(expression)

Here is the aspx

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldName="Reg" HeaderText="Reg" />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="reg" HeaderText="reg" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

Here is the error

Enhanced footers when you expand a detail table

Hello
I am using a fairly old version of rad controls for asp.net ajax (Q3 2008).
I have a master detail grid. In the footer I am showing some basic aggregate details (which I am actually having to calculate manually as the built in aggregates aren't working properly but thats another story) and I am displaying them in the footer by adding literal controls to get a multiline display:

Protected Sub gridJourneys_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles gridJourneys.ItemDataBound

If e.Item.OwnerTableView.Name = "Journeys" Then

If TypeOf e.Item Is GridDataItem Then

Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)

Dim x As TimeSpan = TimeSpan.Parse(dataItem("IdlingTime").Text)

idlingTime = (idlingTime + x)

Dim y As Double = Double.Parse(dataItem("DistanceTravelled").Text)

distanceTravelled = (distanceTravelled + y)

Dim z As TimeSpan = TimeSpan.Parse(dataItem("TimeTaken").Text)

timeTaken = (timeTaken + z)

ElseIf TypeOf e.Item Is GridFooterItem Then

Dim footerItem As GridFooterItem = CType(e.Item, GridFooterItem)

footerItem("DistanceTravelled").Text = distanceTravelled.ToString("F2")

'footerItem("TimeTaken").Text = timeTaken.ToString

footerItem("TimeTaken").Controls.Add(New LiteralControl("Total: " & timeTaken.ToString & "<br/>"))

footerItem("TimeTaken").Controls.Add(New LiteralControl("Idling: " & idlingTime.ToString))

End If

The footer displays fine when the grid first loads but if I expand a row in the table to show the details table then the footer information for TimeTaken column (which was created using literal controls) is lost. The DistanceTravelled column is fine

thanks

How To Test Whether Upload/Download Was Successful

Hi,

I am using the FileExplorer and I have EnableAsyncUpload set to true. I have also applied these modifications so that the Open menu option will always force a download.

With the Telerik AsynchUpload control, I can use the OnClientValidationFailed to verify the status of an upload. I need to be able to do this when clicking the Upload toolbar button within FileExplorer. But I don’t want to validate a “failed” upload; I want to validate a “successful” upload.

And I’m not sure that either test can be preformed when forcing a download, since I am actually invoking my browser’s “Save As” feature, as opposed to a Telerik download feature.

Any suggestions?
Thanks,
Steven
