Setting various control BackgroundColor's OnClientDragging

Hi All,

I am attempting to achieve the following functionality: I would like to change the background color of the control the user's mouse is currently over when the user is dragging an item.

Reasoning: I allow the user to drag-and-drop items from a RadListBox onto the page. This drag-and-drop functionality creates RadDocks. Once a RadDock is on the page it set's its RadDockZone is forbidden to all other docks. As such, if I had two docks on the page, I indicate that a 3rd RadDockZone is a viable move option by changing that DockZone's background color to green. I would like this functionality to extend to when the user is first creating their RadDock -- I would like DockZone currently being hovered-over to turn green.

Is this possible? I'm looking through the OnClientDragging event, and I can see that it can return (X,Y) coordinates through use of the get_domevent() method. Is there a way to translate this hit coordinate into the control located at the coordinate?

Thanks for your time,

Sean Anderson

Modal Pop up extender

Hi All,

I am adding comments to the database by opening the modal pop up extender. User can type the comment in the modal pop up text box and as soon as the user clicks Ok button, the comments go to the database, and i pull those saved comments from database and display them in the grid.
Everything works fine except when I put the ajax panel around the Ok button, the display of the saved comments stopped right away. I am not sure what am I doing wrong. Below is my code

<asp:LinkButton ID="lnkComments" runat="server" Text="Add Comments"></asp:LinkButton>

<div>

<asp:Panel ID="panel1" runat="server" CssClass="modalPopup" Style="display: none"

Width="500px" BackColor="#E6E6E6">

<p>

Please add the comments</p>

<asp:TextBox ID="txt_comments" runat="server" TextMode="MultiLine" Width="480px"></asp:TextBox>

<div>

<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel_Ok" LoadingPanelID="RadAjaxLoadingPanel1">

<asp:Button ID="OkButton" runat="server" Text="OK" OnClick="OkButton_Click" CommandName="Ok" />

<asp:Button ID="CancelButton" runat="server" Text="Cancel" />

</telerik:RadAjaxPanel>

</div>

</asp:Panel>

</div>

<div>

<asp:ModalPopupExtender ID="ModalPopUp_Comments" runat="server" TargetControlID="lnkComments"

PopupControlID="panel1" BackgroundCssClass="modalBackground"

CancelControlID="cancelButton" DropShadow="true">

</asp:ModalPopupExtender>

</div>

and the code behind is

protected void OkButton_Click(object sender, System.EventArgs e)

{

ModalPopupExtender ModalPopUp_Comments = (ModalPopupExtender)RadGrid_cDetailsView.MasterTableView.Items[0].FindControl("ModalPopUp_Comments");

TextBox txt_comments = (TextBox)RadGrid_cDetailsView.MasterTableView.Items[0].FindControl("txt_comments");

RadGrid RadGrid_cComments =(RadGrid) RadGrid_cDetailsView.MasterTableView.Items[0].FindControl("RadGrid_cComments");

ModalPopUp_Comments.Hide();

cComments comments = new cComments();

CiscHeader cHeader = new CiscHeader();

cHeader.cId = Request.QueryString["ID"];

if(txt_comments.Text != "")

{

//comments.UserId = HttpContext.Current.User.Identity.Name;

// for testing purposes only

comments.UserId = "Anjali";

comments.UserComment = txt_comments.Text;

}

cHeader.AddcComments(comments);

cScoringCtrl cscoringCtrl = new cScoringCtrl();

cscoringCtrl.savecComments(cHeader);

txt_comments.Text = string.Empty;

cHeader.cComment.Clear();

cscoringCtrl.getcComments(cHeader);

RadGrid_cComments_Bind(cHeader, RadGrid_cComments);

}

radGrid_cComments_Bind , refreshes the gris and shows the user comments right away.

Any help will be appreciated.

Simple Feature Request

You know how you decorate the control with the NoBorders class...?

Can you also decorate it with a Scrollable class if the control has scrolling enabled?

For my .skin file I would like to always have NoBorders, however IF it's in scrolling mode, I'd like a bottom border. But with the rendered CSS I don't seem to be able to do that.

Again, just to clarify....this is a feature request as you cannot use custom code to define a .skin file :) So I don't need a sample, I'd just like to know in the CSS when this option is toggled.

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?
