Good Day/Evening,

I'm having some problems with the setting the datasource of 3 radgrid controls each in it's own RadPageView in the Multipage for a tabstrip.

E.G

RadGridUsers
Column 1 Column 2 Column 3 SelectButton

TAB 1 | TAB 2 | TAB 3

MULTIPAGE
----------------
RADGrid1
----------------
RADGrid2
----------------
RADGrid3
----------------

Now what I'm doing is when I get a SelectedIndexChanged event from RadGridUsers, i want to set the RadGrid1,RadGrid2 and RadGrid3's datasource to Nothing (Null in C#) before I update the grids with new data. The problem I'm having is that the Grids Row Count of RadGrid1, RadGrid2 and RadGrid3 is still greater than 0 even after I set the datasource to Nothing.

Private Sub RadGridUsers_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGridUsers.SelectedIndexChanged

'Clear all Grids of any previous account's data

RADGrid1.DataSource = Nothing

RADGrid1.DataBind()

RADGrid2.DataSource = Nothing

RADGrid2.DataBind()

RADGrid3.DataSource = Nothing

RADGrid3.DataBind()

Select Case TabStrip.SelectedTab.Text

Case "TAB 1"

RADGrid1.Datasource = GetProfile

RADGrid1.DataBind()

Exit Select

Case "TAB 2"

RADGrid2.Datasource = GetAddressDetails

RADGrid1.DataBind()

Exit Select

Case "TAB 3"

RADGrid3.Datasource = GetOrderHistory

RADGrid1.DataBind()

Exit Select

End Select

End Sub

After I set all the RadGrid's Datasource to nothing and then only update the selected tabs RadGrid, I want the user to selecte another TAB (e.g TAB 3) and what I do then is check if the TAB3's RADGrid has any Items by doing this

Private Sub TabStrip_TabClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTabStripEventArgs) Handles TabStrip.TabClick

Select Case e.Tab.Text

Case "TAB1"

If Not RadGrid1.Items.Count > 0 Then

RadGrid1.Datasource = GetProfile

End If

Case "TAB2"

If Not RadGrid2.Items.Count > 0 Then

RadGrid2.Datasource = GetAddressDetails

End If

Case "TAB3"

If Not RadGrid3.Items.Count > 0 Then

RadGrid3.Datasource = GetOrderHistory

End If

End Select

End Sub

My Problem is that the item count is always greater than 0 even after I've set the Datasource to Nothing and then did a RadGrid.DataBind.

Your help would be much appreicated.

Combining Skin CSS Files

Is there a way I can utilize the skinning functionality for the RadWindow, but instead of keeping the CSS files in the /skins/ folder (/skins/Window.css and /skins/MySkin/Window.MySkin.css), merge them into my site CSS file? I am working on site optimization and I would like to remove the 2 extra server calls.

Does MaxJSONLength in web.config affect RadTreeView?

Hello,

I have a RadTreeView control that fails with the following error, if I populate it with a large (say, 2000) number of nodes:

"Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property."

I am able to set the maxJsonLength property in the web.config of my application - however no matter what value I give to maxJsonLength (up to Int32.MaxValue), the above error appears. I've tried every combination of maxJsonLength value and number of nodes in my tree.

In the Microsoft docs (http://msdn.microsoft.com/en-us/library/system.web.configuration.scriptingjsonserializationsection.maxjsonlength(v=VS.90).aspx), it says:

"The value of the MaxJsonLength property applies only to the internal JavaScriptSerializer instance that is used by the asynchronous communication layer to invoke Web services methods."

So now I'm thinking that RadTreeView doesn't pay attention to maxJsonLength. Is this correct?

Thanks,
Leigh

Default height of a RadScheduler display the TimeLine view?

How can I set the default height for a RadScheduler that's using the timeline view? I don't want to set a fixed height, cause I want it to grow vertically when I add resources.

Thanks

RadDateTimePicker and invalid content

Hi,

When I enter some invalid data into a RadDateTimePicker, the field is marked as invalid (warning triangle and red border)- That's nice and fine.
But when I submit the form, however, the page is considered as valid (this.IsValid returns true) and the postback is executed.

How can I prevent the form to do a postback on invalid data?

Thanks in advance.

Can't select items, just text

Hi,

One of my users is having an issue with selecting items in a RadListBox. When they click on an item in the ListBox, characters in the text of the item is highlighted, but the actual item is not selected. It is very strange behaviour. This problem is occuring in all browser, but only on one particular computer. I have not been able to replicate the problem myself It has me completely stumped. Does anyone have any ideas what could be causing this?

See the attached screenshot for an example of the problem. The user has clicked on the fifth item in the listbox (Hulland) but as you can see the text "Hulland" gets highlighted, but he listitem is not selected.

Thanks
Andrew Dixon
