Don't allow negative value in RadNumericTextBox

Hi,
I have widely used RadNumericTextBox in my application. I want to restrict the user to enter negative value in the RadNumericTextBox without set to MinValue = 0. We can set MinValue=0 but in this case also user can enter the negative value however it will be set to 0 by default.
But i don't want to allow the user to enter negative values in entire application. Can anyone have solution to solve this issue ?

HeaderText is not working in a grid inside RadWindow

Good day.
I need to change, in the Page_Load event, the grid header.
I'm using the code grdArticoli.MasterTableView.GetColumn("Codice").HeaderText = 'SOME TEXT' but nothing happen if the grid is in a RadWindow control. The same line of code is working fine if the grid is not in a RadWindow.
Another element: after some work in the RadWindow and after another postback the header text is changed !
What's wrong ?

Div or Panel loading in sequence

Hi All,

How can I load my panels in sequence? For instance I have 3 panels or Divs (Header, Right and Main). During page load, I wanted to load the Header first for it is just a simple text or it can load both the Header and the Right Panel at the same time, my Right Panel has treeview and it would take a bit of time coz its populated dynamically. And last to load is the Main Panel(with Radgrid) after both the header and the Right Panel is completely loaded. The reason I want to make this sequence coz my grid has a thousand records, right now user see only white page which takes time before it loads the whole page. If there can be a sequence of loading they will see right away the header and the right panel and they will just wait for the main panel to load (with loading image) which is better to see rather than seing only white page for some time.

Thanks in advance,
RJ

Special characters in RadComboBox and Ajax

I use a RadComboBox with items filled at run-time. The values comes from an entries made by users so I don't have control on them. Also I add the generic item "<No selection>". Without using Ajax, all work fine. But when I put this combo box into a RadAjaxPanel and react to the OnTextChanged event to change the visibility of other controls, in Visual Studio I receive an exception when I select the "<No selection>" item. When the page is first shown, if it's the selected item then no error is thrown, but same thing if I select it.

I discover the problem come from the "<" and ">" characters. So if I replace my text to "[No selection]" then it work! Because I have no control, and don't want to, on values of the list I need to find a solution for this.

I tried to replace them by equivalent code ("<", ">") with no success. I also tried Server.HtmlEncode("<No selection>")but same thing. I also try the second technic as described in http://www.telerik.com/support/kb/aspnet-ajax/combobox/using-displaying-special-characters-in-radcombobox.aspx.

---------------------
I tried the demo located at http://demos.telerik.com/aspnet-ajax/combobox/examples/configurator/defaultcs.aspx and when I enter the value "<No selection>" in the Empty Message field then the entire page is gone! These characters are "killers"...

Hide row on inline edit

I have a grid and am using javascript to hide text and label based on the value of a dropdown within the same grid, during an Insert. Now using server side code on itemCommand in edit mode i need to check one field and hide another row based on value of first. The row I need to hide is a GridBoundColumn. I have been able to hide the textbox, but the label is still there. How can I hide the whole row so that none of this appears?

RadTreeView click issue

Hellow,

We are working with RadTabStrip for RadMultiPage. There are three userControls A, B and C for each RadPageView as PageViewA, PageViewB and PageViewC. UserContol B and C are put in userControl A when page load. I have a button in userControl A, click it go to PageViewC which has a RadOrgChart and RadTreeView for list customers. 

(Due to RadOrgChart not fire Click event, So we add radTreeView can be clicked). We need to click Treeview node, then let PageViewA be selected(e.g. let PageViewA tab selected as active tab). Now the problem is after click any Treeview node, it always keep in PageViewC tab afte postback. We have OnNodeClick="RadTreeView1_NodeClick" for RadTreeView and sub as below:

Protected Sub RadTreeView1_NodeClick(ByVal sender As Object, ByVal e As RadTreeNodeEventArgs) Handles RadTreeView1.NodeClick

Dim rpv As RadPageView = CType(UserControlA.FindControl("PageViewA "), RadPageView)

rpv.Selected = True

End Sub

Please advise, how to do the PageViewA tab can be selected after click a treeview node on PageViewC

Thanks in advance.
