Display Loading Panel during Radgrid Export

Hello,
I have a Telerik Radgrid with Export to Excel, CSV and Word buttons on it. Since I am exporting huge amounts of data it takes some time for the Save pop up to display. Is there any way to specify the user that some background work is going on in order to prepare the excel or csv during that particular period of time.

I have gone through the following post, but I could not get an ideal solution.
http://www.telerik.com/community/forums/aspnet-ajax/grid/display-loading-panel-during-export.aspx

Could you suggest me any alternative such as the mouse icon turning to an hour glass or a loading panel getting displayed during the time etc?

Thanks,
M N V Koundinya

Get the index number of the listbox item?

Hi

I am updating an old project to use some of the Telerik controls - I am new to your controls. A standard ASP.NET Listbox was previously used in a modal popup to re-order items in a list - once the user was happy with the new order of items they click a 'Save Order' button to save the new order of items and close the popup. The function that works fine and does this is:

Protected Sub SaveOrder(ByVal sender As Object, ByVal e As EventArgs)

Dim intID As Integer

Dim intIndex As Integer

Dim strUpdate As String

Dim cmdUpdate As SqlCommand

connTC.Open()

For Each item As RadListBoxItem In ListBox1.Items

'get the ID of the item

intID = item.Value

'get the index number in the listbox

intIndex = ListBox1.Items.IndexOf(item)

'increase by 1 since listbox index starts at 0

intIndex = intIndex + 1

strUpdate = "Update tblGalleryImages SET fldOrder=@fldOrder WHERE fldGalleryImageID=@fldGalleryImageID"

cmdUpdate = New SqlCommand(strUpdate, connTC)

cmdUpdate.Parameters.AddWithValue("@fldOrder", intIndex)

cmdUpdate.Parameters.AddWithValue("@fldGalleryImageID", intID)

cmdUpdate.ExecuteNonQuery()

Next

connTC.Close()

'hide the modal popup

ModalTextPopup.Hide()

End Sub

I have tried applying the same function to the RadListBox (ID =ListBox1) . I have made the following change on one of the lines:

" For Each item As RadListBoxItem In ListBox1.Items"

However there is an error on the following line:

intIndex = ListBox1.Items.IndexOf(item)

I can not get the index of the Radlistbox item. The error is:

'Telerik.Web.UI.ControlItemCollection.Protected Friend Overridable Function IndexOf(item As Telerik.Web.UI.ControlItem) As Integer' is not accessible in this context because it is 'Protected Friend'.

Any help in getting the index of the Radlistbox item would be appreciated. The 'save order' must be done with an 'external' button as the user must be happy with the display order etc. before they save it - in other words I can not use Autopostback etc.

Thanks in advance.

add nodes dynamically with nodetemplates

hi i got problem, adding new nodes dynamically.
the nodetemplates are assigned by the templateneeded event:

protected void tree_TemplateNeeded(object sender, RadTreeNodeEventArgs e)

{

ANDNode x=new ANDNode();

e.Node.NodeTemplate = x;

}

my root node is a dropdownlist and when i change the selected index of the ddl, new child nodes should be added to the node.
My problem is, that the selectedchangedindex event will be not performed. Do you have an idea, why it will be not performed?

public class ANDNode : ITemplate

{

public ANDNode()

{

}

public void InstantiateIn(System.Web.UI.Control container)

{

DropDownList ddl = new DropDownList();

ddl.AutoPostBack = true;

ddl.ID = "ddl"+Guid.NewGuid().ToString();

ddl.DataBinding+=new EventHandler(ddl_DataBinding);

ddl.SelectedIndexChanged += new EventHandler(ddl_SelectedIndexChanged);

container.Controls.Add(ddl);

}

void ddl_DataBinding(object sender, EventArgs e)

{

Global.FillExpressionItems((DropDownList)sender);

}

void ddl_SelectedIndexChanged(object sender, EventArgs e)

{

DropDownList ddl = (DropDownList)sender;

RadTreeNode node = (RadTreeNode)ddl.NamingContainer;

node.ExpandMode = TreeNodeExpandMode.ServerSide;

node.Expanded = true;

RadTreeNode child = new RadTreeNode();

child.NodeTemplate = new ANDNode();

node.Nodes.Add(child);

}

FolderView vs FileView

Is there anyway to setup the FileExplorer so the right hand "FileView" side excludes folders and only shows files? I'd like to use the left hand "FolderView" side for navigation through my directory structure, and the right hand side for only accessing files.

P.S. Is there any way to hide the address/path bar?

[Solved] Telerik JS Intellisense in separate JS file.

Hi all,

I've read the post here: http://www.telerik.com/support/kb/aspnet-ajax/general/adding-visual-studio-intellisense-support-for-radcontrols.aspx and then I noted a forum post showing how to get this functionality in a separate JS file.

So, I have this:

//Dashboard.js
/// <reference name="MicrosoftAjax.js"/>
/// <reference name="Telerik.Web.UI.Common.Core.js" assembly="Telerik.Web.UI"/>

and then I have Dashboard.aspx reference Dashboard.js:

<telerik:RadScriptManager ID="ScriptManager1" runat="server" EnableTheming="True" EnablePageMethods="True">

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

<asp:ScriptReference Path="~/Scripts/Dashboard/Dashboard.js" />

</Scripts>

</telerik:RadScriptManager>

I continue to not see the intellisense shown in screenshots. Doing $telerik does not find anything in the intellisense dropdown.

What am I doing wrong?

Thanks,

Sean

[Solved] How to highlight current date in DateTimePicker

Hi,
I want to higlight the current date in the rad date time picker, if a user selects any other date, other than today, today's date should still be highlighted, while he selects other date of his desire. I want to higlight today's date, so that it serves as a reference to user, just in case he forgets what today';s date is. Please help.

[Solved] Google-like filtering on a treeList

HI,

Well, I think that the title say almost everything : How can I do a google-like filtering on a treeList like in this demo (is it even possible ?). Look like I just have to use a RadFilter (cause it seem that there is no filtering propriety for a treeList) and override it, but I don't know how to do so.

Thank you in advance for your answer,
David

PS: Well, in fact, I have another question : is it possible to filter a treeList ? I tried a radFilter, but it doesn't seem to work. And I read here that treeList doesn't support filtering. So, is it only me or the treeList isn't compatible with a radFilter.
