Hello again.

I have a nested grid scenario, and on updating a record in the child grid, I need to ReBind() the parent grid.

e.Canceled = true;
grdProfileIntakes.Rebind();

However, doing this collapses the grid. I need it to refresh and then expand the appropriate nodes to where it was. Going through the documentation, I think I have two possible solutions. First is using Grid.SelectedIndexes.Add(indexOfSelectedParentTableRow, indexOfParentTable), second is using Grid.MasterTableView.Items[indexOfSelectedItem].Expanded = true.

Both methods need the index of the selected item, specifically the index of the parent of the selected child item. How can I get this value?

TIA

[Solved] Empty RadDockZone Message

I would like to have a message displayed on top of the RadDockZone when there are no RadDocks on it. This will help the user better know that it is ready and waiting for RadDocks to be added to it.

I have worked through a possible solution with the AjaxLoadingPanel, showing it when RadDockZone.get_docks().length = 0, but I keep getting the "object is null" javascript error.

    
            if ($find("<%=rdzLeft.ClientID%>").get_docks().length == 0)  
        
            {  
        
                var objEmptyZoneLoadingPanel = $find("<%=lpEmptyZone.ClientID%>");  
        
                objEmptyZoneLoadingPanel.show("<%=rdzLeft.ClientID%>");  
        
            }

I've also considered having <div>s displayed over top of each RadDockZone, only showing them when the associated RadDockZone is empty. I was having a difficult time setting the style of these <div>s to appear where I wanted them.

    
            <!-- Empty RadDockZone messages --> 
        
            <div runat="server" id="divEmptyLeftZone" class="DashboardItemPanelLeft_Empty">No Dashboard Items (Left)</div> 
        
            <div runat="server" id="divEmptyRightZone" class="DashboardItemPanelRight_Empty">No Dashboard Items (Right)</div> 
        
            <!-- RadDockLayout for dashboard items to go --> 
        
            <telerik:RadDockLayout runat="server" ID="rdlDockLayout">  
        
                <telerik:RadDockZone runat="server" ID="rdzLeft" MinHeight="300px" CssClass="DashboardItemPanelLeft" HighlightedCssClass="HighlightedZone" /> 
        
                <telerik:RadDockZone runat="server" ID="rdzRight" MinHeight="300px" CssClass="DashboardItemPanelRight" HighlightedCssClass="HighlightedZone" /> 
        
            </telerik:RadDockLayout>

Are there any built-in ways to address my goal? Perhaps an "EmptyZoneMessage" for the RadDockZone?

Upgrading to VS2010

We are a shop that currently uses VS2008. We would like to upgrade our apps to VS2010 initially using the 3.5 framework. Sometime later, we would like to upgrade our apps to the 4.0 framework.

We had an architect in our company try and convert VS2008 to VS2010 project and worked fine except for the Telerk tools. He could not get the present version of the DLL to work. Our current version is: 2009.3.1314.35

What is the proper upgrade path in order to accomplish the above scenario?

Treelist DataBind

Hi,

I am having a result set with the structure of
Level1                         Level2          Level3               CalcField

Akron                Cleveland OH         2007-QTR 1     206172.0000
Akron                Cleveland OH         2007-QTR 2     225291.0000
Akron                Cleveland OH         2007-QTR 3     210866.0000

Mobile Controls

I was wondering if Telerik has plans to create a mobile controls bundle that is based on the ASP.Net AJAX controls and skins. I noticed component one has a mobile and iphone products out (very limited selection i must say) and was hopping Telerik will do the same sooner or later. As far as i know there aren't many controls for mobile websites out on the market, and I personally would like to keep my mobile websites consistent with their desktop versions. I know in theory we can use the .net controls but they do seem to add a lot to the size of a page.

Compatibility issue in RadWindow

Hi,

I have used Radwindow in my project which returns location value that is selected in that window.. I have used javascript for returning location value.. The Problem is it works fine in IE8 browser, but the value is not getting returned in Safari..

<telerik:RadWindowManager ID="RadWindowManager2" OnClientShow="" runat="server" OnClientClose=""

ReloadOnShow="false">

<Windows>

<telerik:RadWindow ID="radWindowLocationPopup" OpenerElementID="" OffsetElementID=""

ClientCallBackFunction="CallBackFunctionService" Behavior="Close" VisibleTitlebar="false"

Modal="true" Width="578px" runat="server" Height="450px" NavigateUrl=" " VisibleStatusbar="false">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

and the code in javascript are,

function OpenRadWindowLocaltionPopup(externalScheduling) {

var Url = "./Locationpopup.aspx?EnableScheduling=" + externalScheduling;

var oWnd = radopen(Url, "radWindowLocationPopup");

oWnd.SetUrl(oWnd.GetUrl());

return false;

}

function CallBackFunctionService(radWindow, returnvalue) {

try {

if (returnvalue != "") {

var textBoxLocation = document.getElementById("ctl00_ContentPlaceHolder1_textBoxExternalLocation");

var hiddenLocationID = document.getElementById("ctl00_ContentPlaceHolder1_hiddenFieldLocationId");

var hiddenLocationName = document.getElementById("ctl00_ContentPlaceHolder1_hiddenLocationName");

var rtnValue = returnvalue.split("~");

hiddenLocationID.innerText = rtnValue[1];

textBoxLocation.value = rtnValue[0];

hiddenLocationName.value = rtnValue[0];

}

else {

document.getElementById("ctl00_ContentPlaceHolder1_textBoxExternalLocation").value = "";

}

CheckExternalSchedulingEnable();

}

catch (err) {

}

return false;

}

Do i need to do any change in javascript to make it work efficiently in safari.. Please guide me..

Thanks,
Hema.

Restricting Scheduler's height to 100%

Hi there.

I have a scheduler that I would like to expand to 100% of the available screen, but NOT expand beyond that. Setting the height of the Scheduler to 100% and then the overflow behaviour to EITHER scroll or expand does not seem to do the trick - in both instances, the scheduler expands to extend the height of the window. This is a problem because Chrome and IE do not seem to like it when you drag appointments higher or lower up the screen (ie require an "automatic" scroll) if it is the window's scrollbar that must be used instead of the schedulers.

I can set the height of the scheduler to say 1000 pixels to get the functionality that I'm after, but of course I won't necessarily know the height of the window. And I can set the height with javascript onload etc, but that gets messy when dealing with ajax postbacks and dealing with window resizes etc. Am I missing something simple?

Thanks,

Matthew

Notify user when Insert/Update/Delete succeeds or fails

Hello,

I have a RadGrid I am using for customer maintenance. I would like the users to be able to insert, update and delete customers from this RadGrid. I'd also like to notify them that "Insert for customer: XXXXXX succeeded", "Customer XXXXXX updated" or "Unable to delete customer XXXXXX" after the insert/update/delete either succeeds or fails. Since I am setting the RadGrid's DataSource property in the RadGrid1_NeedDataSource event, I don't think that I can use AllowAutomaticDeletes, AllowAutomaticInserts, or AllowAutomaticUpdates along with the ItemDeleted, ItemInserted, or ItemUpdated events (if I can, I must have been doing something wrong).

Is there a way to notify the user the status of the operation without setting the RadGrid's DataSourceID and enabling Automatic operations?

Thanks,
Casey

***EDIT - I was able to accomplish this by setting a session variable in the ItemCommand of the RadGrid and then adding a new literal control to the end of the RadGrid with the session variable text as the message.
