Drag & Drop outside a DestinationHtmlElement

Hello,

I am doing some functionality with drag & drop effect in which I have to drag from one listview to another listview and also in the same listview for reordering purposes. What happens is that I can't capture the drop when user drops inside the listview but outside an html element (LinkButton, Label, etc).

What I tried to do was to put in my ItemTemplate a div running at server and then tried with a Panel containing the data I'm showing in the ListView, so my codebehind could capture this as a htmlElement, but it won't, DestinationHtmlElement is an empty element.

What should I do??

I was looking the ListBox aproximation and the drag & drop example is more or less what I am looking for, but I did not use that because I have to customize the List content as a Link followed by a Label and also it shouldn't have a scroll but it should have a variable height depending on the ammount of data it has

Hope you can help me soon, and if you didn't understand me just let me know

Thanks in advance,

Camilo

How do i Line break in tooltip?

Hi,

I am using RadToolTipManager control and displaying tooltip. Tooltip text i am reading from the database.
for normal text i am able to display tooltip with no problem, but in my text there are carriage return characters (like \n \r),
that causes problem and does not display and gives me error.

Please see code:

private void PopulateQuestion()

{

lblSectionName.Text =

this.Question.PageTitle;

divSection.Visible = (

this.Question.PageTitle != string.Empty);

lblQuestionSequence.Text =

"Q." + this.Question.Sequence.ToString() + " - ";

lblQuestionText.Text =

this.Question.QuestionText;

// Set help icon alt text

//imgHelp.AlternateText = this.Question.AdditionalContent;

//imgHelp.Attributes.Add("title", this.Question.AdditionalContent); // For FireFox

// string s = "Khwaja \n saiyed";

// string newstr = s.Replace("\n", "<br/>");

//this.RadToolTipManager1.TargetControls.Add(imgHelp.ClientID, s.ToString(), true);

this.RadToolTipManager1.TargetControls.Add(imgHelp.ClientID, this.Question.AdditionalContent.ToString(), true);

}

protected void RadToolTipManager1_AjaxUpdate(object sender, Telerik.Web.UI.ToolTipUpdateEventArgs e)

{

Label lblInsideToolTip = new Label();

lblInsideToolTip.Text = e.Value;

e.UpdatePanel.ContentTemplateContainer.Controls.Add(lblInsideToolTip);

}

I hope this makes sense to all of you.

Thanks

RadEditor - commandName is undefined on client paste

Hi,
I' working with the version 2014.2.724.45 and our standard is IE9 and I have problems with the clientPasteHtml. My test page is very simple:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TelerikRadEditorPaste.Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<script type="text/javascript">

function onClientPasteHtml(editor, args) {

var commandName = args.get_commandName();

if (commandName == "Paste") {

alert('OK --> CommandName = ' + commandName);

} else {

alert('NOT OK --> CommandName = ' + commandName);

}

</script>

<asp:ScriptManager runat="server"></asp:ScriptManager>

<telerik:RadEditor ID="radEditorMandate" runat="server" Width="856px" Height="590px" StripFormattingOptions="NoneSupressCleanMessage, ConvertWordLists, MSWordNoMargins" OnClientPasteHtml="onClientPasteHtml">

<ContextMenus>

<telerik:EditorContextMenu TagName="*">

<telerik:EditorTool Name="Paste" />

</telerik:EditorContextMenu>

</ContextMenus>

<Tools>

<telerik:EditorToolGroup>

<telerik:EditorTool Name="Paste" />

</telerik:EditorToolGroup>

</Tools>

<CssFiles>

<telerik:EditorCssFile Value="~/RadEditor.css" />

</CssFiles>

</telerik:RadEditor>

</form>

</body>

</html>

If we use the keyboard to paste text (ctrl+v), the command name is OK (Paste), but if we use the toolbar or the context menu, the command name is not OK (undefined)

Could you help to solve this problem??

I tested with IE11 and I meet the same behavior.

Thank you and have a nice day.

Hover over sub item

Hi there,

I am using a custom skin build with the Visual Style Builder and I am having trouble implementing the following scenario:

When I hover over a main item the color of the main item changes from Red to White, which is OK (see Main item hover.png)
When I hover over a sub item I want the color of the Main text item still be White. Now it changes back to Red (see Sub item hover.png).

Anybody any idea?Thanx!

RadWindow Does Not Open

Hi All,

Very odd behaviour here...pretty basic radwindow. Opens based on Hyperlink ElementOpenerID.
See the page here: http://dcmapsa.azurewebsites.net/map.aspx

Bottom left under Help, there are 3 links. They should open 3 different windows. Simply does not work. My guess is code conflict somewhere.

Odd thing is that it works on this page without issue...
http://dcmapsa.azurewebsites.net/default.aspx

Anybody got any ideas on this glitch?

Thanks
Brett

RadGrid - Submitting rows to database

Hi,

I have a grid I am converting from an Infragistics WebGrid to a Telerik RadGrid. It is a relatively simple grid. I need to submit the rows after an entire form is filled out. There can be one to many rows. I have tried this in a sub that gets called when entire form is submitted:

For Each row As GridDataItem In RadGrid1.MasterTableView.Items

but it always returns false

Am I doing this correctly? Does it actually have to be done as a grid event somehow? How would I do that if I don't want to submit it until a user clicks an asp submit button. I'm using vb.net by the way.

Thanks for your help!

Set RadGrid to keep pagesize when groups are collapsed

Hi,

I have a question about the RadGrid when you use both paging and grouping. If all the groups are expanded it works fine. But if i collapse a couple of groups, the rowcount of the group are still counted as if they where expanded?

For instance if I have 5 groups with 10 rows each and a pagesize of 20. When I start the page all the groups are expanded, and the first page is shown with 2 groups of 10 rows each. That is good beacuse I want to show 20 rows on each page. But then if I have a "Collapse All"-button that I press, there is only 2 rows showing on my first page? The 2 groups collapsed is only 2 rows but is counted as if thay where expanded?

Is there any way to solve this? I want the page to show as much data as I have set in the pagesize.

This is my grid (I have tried both Client and Server GroupLoadMode):

<telerik:RadGrid ID="RadGridBuyWarrants" runat="server"

OnNeedDataSource="RadGridBuyWarrants_NeedDataSource" AutoGenerateColumns="false"

AllowSorting="true" AllowPaging="true" PageSize="20"

ShowGroupPanel="false" onitemcommand="RadGridBuyWarrants_ItemCommand"

onitemdatabound="RadGridBuyWarrants_ItemDataBound">

This is my expand/collapse all code:

foreach (GridItem item in RadGridBuyWarrants.MasterTableView.Controls[0].Controls)

{

if (item is GridGroupHeaderItem)

{

item.Expanded =

true;

}

Would be very greatful if anyone could help me solve this.

RadEditor Mixing tags with same meaning.

RadEditor v.21014.3.1024.40

I am having an issue with the Text Align Buttons.

I am loading some html with <p align=''> tags. When I use the editor to change the alignment I am getting the original align element and a style element. Which is causing some bad rendering when I use the html elsewhere.

Original editor Content
<p align=\"center\">TEL: XXX-XXX-3465 • WEB: <a href=\"http://www.wxxxxxxxxxxl.com\">www.wxxxxxxxxxx.com</a></p>

Editor Content after changing alignment to Left
<p align=\"center\" style=\"text-align: left;\">TEL: XXX-XXX-3465 • WEB: <a href=\"http://www.wxxxxxxxxxx.com\">www.wxxxxxxxxxx.com</a></p>

See how it keep the align='center' and added style='text-align: left'

I have the following Filters disabled.
RadEditor2x.DisableFilter(EditorFilters.ConvertTags);
RadEditor2x.DisableFilter(EditorFilters.ConvertFontToSpan);
RadEditor2x.DisableFilter(EditorFilters.ConvertToXhtml);
RadEditor2x.DisableFilter(EditorFilters.FixUlBoldItalic);
RadEditor2x.DisableFilter(EditorFilters.MozEmStrong);
RadEditor2x.DisableFilter(EditorFilters.ConvertInlineStylesToAttributes);

Is the a filter that i need to enable or disable that will correct this?

Additionally, I would prefer that the alignments render as align = ' ' not style = ' '
