I have a rad panel that I have put a rad tree view in. However, now that the rad tree is within the panel, I cannot get it to collapse. It is always expanded and won't collapse even if you click the button. The two other panels have static data in them and they collapse fine. Can anyone help me with this issue? Here is my code

Is there a way to skin the RadMultiPage so that it appears to blend with the selected tab? I am using the Office2007 skin and would like the background underneath all my rad page views to have the same blue shade that is the very bottom row of pixels on the selected tab.
In the future, I would like to allow users to select their own skin, so if there was a non-hardcoded way to do this, I would really prefer it.

Hello,
I am adding a row to a child grid in the OnInsertCommand event. This is working as expected. But I would like to move to the last page in the grid and select the row that was just inserted. I am doing the following, but I always remain on the first page of the child grid.
In this example, "Systems" is the name of the Detail grid view.
also, is there away to do this without doing so many rebind calls?
Thanks

Hi,
I was using RADGrid Q3 2007 release, in that the following highlighted properties were available:
<radG:RadGrid ID="rgMemberResult" BackColor="white" runat="server" AllowPaging="true" AutoGenerateColumns="false"
EnableAJAX="true" EnableAJAXLoadingTemplate="true" LoadingTemplateTransparency="20"
EnableOutsideScripts="true"
<ClientSettings ApplyStylesOnClient="true">
</radG:RadGrid>
When i upgraded the control to Q2 2009 release, the above specified properties were not supported. Seems to be that they are obsolete. Please let me know, whether any alternate properties available or by default it does support those properties?
Thanks

I would like to have the statusbar, but it should be empty. I set VisibleStatusbar="true". On the client side I call oWnd.set_status(''); . As a result of that, I have the statusbar visible and during loading it has no information. But unfortunately, when the it's loaded, the statusbar has the url. Is there any way not to have the url information in the statusbar, but have it visible?
Thank you,
Tatiana

Hi,
I want to restrict user to select/browse only restricted files, like in html file upload control we have a property called 'Accept' which will take the parameters as file types with cama seperated.
ex: <input type="file" accept="image/jpg,image/png" name="file1" />
I want to know whether this property is availabe in Rad Upload control?
Thanks.

Hello,
I am trying to setup my Radgrid to select multiple rows. After following the demo (http://demos.telerik.com/aspnet-ajax/grid/examples/client/selecting/defaultcs.aspx), everything works great with one exception. I can not select or deselect rows using the Ctrl Key. The Shift Key works as expected.
Here is my code:
| <telerik:RadGrid ID="radgrdEvaluator" Skin="Vista" AutoGenerateColumns="False" AllowPaging="True" AllowSorting="True" AllowMultiRowSelection="True" ShowStatusBar="False" PageSize="10" GridLines="None" width="96%" HorizontalAlign="NotSet" Visible="False" runat="server"> |
| <MasterTableView DataKeyNames="EvaluatorID"> |
| <Columns> |
| <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn"></telerik:GridClientSelectColumn> |
| <telerik:GridButtonColumn ButtonType="LinkButton" DataTextField="EvaluatorID" HeaderText="EvaluatorID" CommandName="Select"></telerik:GridButtonColumn> |
| <telerik:GridBoundColumn DataField="EvaluatorStatus" HeaderText="EvaluatorStatus" DataType="System.Boolean"></telerik:GridBoundColumn> |
| </Columns> |
| </MasterTableView> |
| <ClientSettings EnableRowHoverStyle="True"> |
| <Selecting AllowRowSelect="True" /> |
| </ClientSettings> |
| <pagerstyle mode="NextPrevAndNumeric" AlwaysVisible="True" /> |
| </telerik:RadGrid> |

I'm doing customization of FileExplorer but I've got strange strings like "Common_Open," "Common_Select" in the tooltips and buttons. Since I didn't put any string like above, it's so weird where they come from. Simply, I want to make the string as just "Open" and "Select" etc.
Any idea?
