accessing checkbox in node on client side

Due to having to disable a checkbox but still have it visible on the client side (using client side javascript to check and uncheck it as items in a grid underneath of it are checked) I have added an asp:CheckBox to a node on the server side with the following code:

RadTreeNode substanceNode = new RadTreeNode(substanceRow["Substance_Name"].ToString(), substanceRow["SUBSTANCE_ID"].ToString());

substanceNode.ExpandedImageUrl =

"~/Images/FolderOpen.gif";

substanceNode.ImageUrl =

"~/Images/FolderClosed.gif";

CheckBox indicator = new CheckBox();

indicator.Enabled =

false;

indicator.Visible =

true;

indicator.ID =

"chkSource";

substanceNode.Controls.Add(indicator);

How can I access this checkbox on the client side to work with it. Here is my client side code where I need to work with this checkbox

for (var i=0; i < nodes.length; i++)

{

if (nodes[i].get_value() == selectedSubstanceId)

{

checkbox = nodes[i].findControl(

"chkSource");

}
}

the rest of the logic is working fine I just can't get the checkbox to work with it.
the findControl returns null.

Any help to figure this out is greatly appreciated.

Thanks

John

RadToolTip with RadDock

Hello!

I have an application where I'm using RadToolTip with RadDock. I have a RadDockLayout with only one RadDockZone and this zone with only one RadDock. Inside the dock I'm showing a lot of images and when you click on one of them the RadToolTip shows up.

The problem is that the tooltip shows up and exceeds the docks boundaries and when I try to close (ManualClose) it, I cannot do it because it loses this functionallity due to it exceeds the docks boundaries.

How can I do to keep the tooltip inside the docks boundaries without it makes scrolling?

Thanks beforehand!

RadGrid inside RadPageview height problem

Hi,
I have 2 RadGrids inside separate RadPageView's inside a RadMultiPage with a a RadTabStrip and the whole lot is in a RadWindow.

The first grid has no Command Item Display and fits perfectly. The second grid has the CommandItemDisplay set to Top and now the bottom of the grid is outside the RadPageView border.

How do I set the height of the second RadGrid so that it fits inside the RadPageView even when it has the Command Item Display ?

I have the latest version of 2008.3.1314.35.

Regards

Programmatically loading Filter Values

I am trying to help the user select filter values by clicking on a grid row and then programmatically loading those values into the filter columns. I have two problems. My columns are automatically generated and columns are not found in the foreach loop. Secondly, the CurrentFilterValue does not seem to accept values.

Thanks for any assistance.

protected void radGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

{

if (e.CommandName == "RowClick" && e.Item is GridDataItem)

{

foreach (GridColumn column in radGrid1.MasterTableView.Columns)

{

string IDx = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex][column.UniqueName].ToString();

column.CurrentFilterValue = IDx;

}

disable move behavior

I have the EditMode set to popup and Modal is set to true. Is there anyway we can disable the move behavior? If you cant, is there a way to keep the background grayed out while you move the modal window. Only the radgrid is grayed out if you move the modal window.

Thanks
Hector

Switch tabs when a Row is double clicked

Hi,

I have a RadGrid under a RadTabStrip. ALL controls on the page are created dynamically. I need that when a Row in the Grid is double clicked, the client side javascript function switches the Tab according to a cell value on the Row. I have reached to the point where I can get my desired value from the Row. I get stuck when I need to reference the RadTabStrip that is being generated dynamically.

    
            <head runat="server">  
        
                <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">  
        
                <script type="text/javascript">  
        
                     <!--  
        
                    function OnRowDblClick(sender, eventArgs) {  
        
                        var dataItem = $get(eventArgs.get_id());  
        
                        var grid = sender;  
        
                        var MasterTable = grid.get_masterTableView();  
        
                        var row = MasterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()];  
        
                        var cell = MasterTable.getCellByColumnUniqueName(row, "CurrRegionName");  
        
                        alert(cell.innerHTML);  
        
                        var tabStrip = $find("<%= TabStrip1.ClientID %>");  
        
                        var selectedTab = tabStrip.findTabByText(cell.innerHTML);  
        
                        tabStrip.commitChanges();  
        
                    }  
        
                        -->  
        
                </script>  
        
                </telerik:RadCodeBlock>  
        
                <title></title>

GridException is not serializable

I'm working with a RadGrid contol. I messed up the DataField properties of its contained GridBoundColumns, and got an exception at runtime. But, because I'm running with SessionState set to 'StateServer', instead of to 'InProc', the exception I saw was about a serialization error:

    
            [SerializationException: Type 'Telerik.Web.UI.GridException' ... is not marked as serializable.]

I switched Session.mode to 'InProc', and quickly discovered the error:

    
            There was a problem extracting DataKeyValues from the DataSource. ...

But I shouldn't have had to do this. If GridException is ever put into the Session, it should be marked as Serializable.

We set SessionMode to 'StateServer' as a matter of course, on our development machines, for the specific purpose of revealing serialization errors during development.

Any web application of significance must be capable of running in a clustered environment. We need to ensure that our implementors have the option of using shared sessions when installing in a clustered environment. So we need to make sure we don't write our code in a way to make that impossible.

Might I suggest that your developers might consider doing the same? True, 'InProc' is what Microsoft's tools default to, but it's not a good default to develop against.

Tooltip not working with RadTextBox

I am trying to add a RadToolTip to a RadTextBox, but it is not working (i.e. nothing shows up when I mouseover the radtextbox). If I swap out my RadTextBox with a regular ASP:Textbox, it works perfectly fine. Is the RadToolTip not compatible with Telerik input controls?? Here is the code that does not work:

<telerik:RadTextBox ID="txtTitle" runat="server" Width="300px" ValidationGroup="vgNewAssign" Skin="Office2007" MaxLength="50">

</telerik:RadTextBox>

<asp:RequiredFieldValidator ID="rfvTitle" runat="server" ErrorMessage="Title is required!" Display="None" ControlToValidate="txtTitle" ValidationGroup="vgNewAssign"></asp:RequiredFieldValidator>

<telerik:RadToolTip ID="ttTitle" Position="MiddleRight" RelativeTo="Element" Skin="Office2007" runat="server" TargetControlID="txtTitle" Text="A brief title for the assignment (required). Limited to 50 characters." Width="300px" AutoCloseDelay="30000" />

Increase Tooltip Z-Index

Hi,
how can I increase the z-index of the tooltip when it is shown?
I use the tooltip with the ModalPopup from the Ajax-Toolkit Framework. The ModalPopups have an z-Index of 10001. When the Tooltip is visible, I think the style with z-index:8000 is applied to it.

Thanx
Christian
