Hi,

I have an issue in edititemtemplate of radgrid.I have a radcombobox on edit of radgrid.The issue is required field indicator "*" is appearing in the next line of the radcombox.i want this "*" and validation message to appear next to the radcombobox.i have tried many ways in HTML.But of no use.Any help would be greatly appreciated.

<

EditItemTemplate>

<telerik:RadComboBox Height="100px" Width="150px" Skin="WebBlue" ID="RadCboBusinessUnit" runat="server"

EnableVirtualScrolling="true" EmptyMessage="Please Select..." MarkFirstMatch="true" AllowCustomText="true" CausesValidation ="false"

Text ='<%# DataBinder.Eval(Container.DataItem,"BusinessUnit" )%>' AutoPostBack ="true" OnSelectedIndexChanged = "RadCboBusinessUnit_SelectedIndexChanged" >

</telerik:RadComboBox>

<asp:RequiredFieldValidator ID="ValidateBusinessUnit" runat="server" ControlToValidate ="RadCboBusinessUnit" ErrorMessage="Value Is Required"></asp:RequiredFieldValidator>

</EditItemTemplate>

FYI -- The below code is actually causing out the issue.

Postback when radwindow is closed

I'm attempting to capture the closing of a rad window and do a postback.

The scenario is this:

1) the RadWindowManager is in the master page with a method to pop the window:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server"

Skin="Office2007"

KeepInScreenBounds="true"

Behaviors="Move, Close"

>

<Windows>

<telerik:RadWindow runat="server" ID="rwGeneral"

AutoSize="true"

Modal="true"

Title=""

OnClientPageLoad="OnClientPageLoad" />

</Windows>

</telerik:RadWindowManager>

function getRadWindow()

{

return $find('<%# rwGeneral.ClientID %>');

}

function openRadWindow(url, Title)

{

var oWnd = getRadWindow();

if (Title) oWnd.set_title(Title);

oWnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Resize)

oWnd.setUrl(url);

oWnd.show();

return false;

}

I pop the window from a web control sitting on a page:

function popBranchPicker()

{

var radWindow = getRadWindow();

radWindow.add_close(radWindow_OnClientClose);

openRadWindow('<%= BranchPickerPopupUrl %>', 'Branch Picker');

return false;

}

function radWindow_OnClientClose(oWnd, args)

{

// clean up the close method

var radWindow = getRadWindow();

radWindow.remove_close(radWindow_OnClientClose);

// refresh here

var btnRefresh = document.getElementById('<%= btnRefreshBMDashboardAndPicker.ClientID %>');

btnRefresh.click();

return false;

}

In the page hosted in the rad window (just a stand-alone page, no master page, etc.) I attach a close handler to cause a post-back:

GetRadWindow().add_close(doClose);

function GetRadWindow()

{

var oWindow = null;

if (window.radWindow) oWindow = window.radWindow; // Will work in Moz in all cases, including clasic dialog

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; // IE (and Moz az well)

return oWindow;

}

function CloseOnReload()

{

GetRadWindow().Close();

}

function doClose()

{

document.forms[0].submit();

}

In the postback I perform a save and then emit javascript to close the rad window:

// some stuff here

RadAjaxPanel1.ResponseScripts.Add("CloseOnReload();");

Everything appears to work just fine, and does in fact work fine the first time. The second time I pop the window from the control, however, I get a javascript error:

Message: Can't execute code from a freed script

I've tried all combinations of add_close(), remove_close(), returning false from JS functions, etc. and I can't get it to work correctly. It seems a little counterintuitive to have to jump through all these hoops to get this functionality anyway, so perhaps there's better way to handle this.

Essentially I'm attempting to have the window perform a code-behind save when it's closed (without having to put a button on the page).

Any ideas?

Thanks

Popup should remain open after clicking Save in a RadGrid popup

I have a RadGrid (Grid1) with Master table edit mode = popup. I have the following code in the commandItemTemplate. The popup is a user control.The popup has some textboxes and another Grid (Grid2).

    
            <CommandItemTemplate> 
        
                                                <table width="100%" border="0" cellspacing="0" cellpadding="0"> 
        
                                                    <tr style="height: 20px"> 
        
                                                        <td style="width: 100%; color: #074768" align="right"> 
        
                                                            <asp:LinkButton ID="lnkBtnAddLocation" runat="server" CommandName="InitInsert" Style="font-weight: bold;
        
                                                                padding-right: 2px; color: #074768;"> 
        
                                                                <asp:ImageButton ID="imgbtn_AddLocation" runat="server" SkinID="AddRecord" CommandName="InitInsert" /> 
        
                                                                Add Location 
        
                                                            </asp:LinkButton> 
        
                                                        </td> 
        
                                                    </tr> 
        
                                                </table> 
        
            </CommandItemTemplate>

If I click on "Add Location" it opens a popup. I enter some data and when I click on save, It closes the popup and inserts the data in the RadGrid. But I want the popup to remain open. This is because I want to have a Save button for saving the textboxes data to Grid1 and a OK button for saving the selections in the Grid2 to the Grid1.

Is it possible to keep the popup open after Inserting data into Grid1?

unable to retrieve checked nodes in tree view

Hi I have a tree view with checkboxes on each node. I have written some javascript to check relevant nodes when parent and child nodes on the tree view.

When i try to iterate through nodes on server side ie

foreach (RadTreeNode node in RadTree.CheckedNodes)

{

string value = node.Text.ToString();

}

the value of CheckedNodes.Count = 0

Here is what I do with the javascript to check nodes

var node = args.get_node();

var parentnode = node.get_parent();

if (!node.get_checked()) {

var childNodes = node._getChildren();

var nodeArray = childNodes.toArray();

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

nodeArray[i].set_checked(true);
