I have been looking around but have not found anyone with my same situation. I am using a control in an edit template inside a radgrid. I have a RadComboBox that on selection populates a panel with custom controls based on the combobox selection. After this or any other post back button is used the grid no longer posts back or functions. This also includes the other text boxes inside that same control. I was thinking this might have something to do with the viewstate but changing that around has no fixed the problem. This may just be something quick that I am missing. Any help would be much appreciated.

RadWindow VisibleOnPageLoad issue

Hello , everyone, I've got a strange issue that just popped up after I upgraded to v.2012.2.607.40.

I've got a RadWindow that has VisibleOnPageLoad set to false. This RadWindow contains a few asp drop down lists, RadComboBoxes, and a RadButton. One of the drop down lists contains an item with the text and value set to "Trial". As long as this item is there, the RadWindow will partially render on page load (If I remove the Item, the window is hidden, as expected). If I change the text and value to anything else, the RadWindow is hidden as expected. I have even tried replacing the drop down list with a RadComboBox with an item that has the same "Trial" text/value and I see the same behavior. I've even gone so far as to remove all other controls from the RadWindow to narrow it down to this, so if I have this markup, the RadWindow is shown on page load even if VisibleOnPageLoad is false:

<telerik:RadWindow ID="radWindowNew" runat="server" Modal="true" Behaviors="Close"

Skin="Windows7" Width="400" Height="350px">

<ContentTemplate>

<table border="0" cellpadding="2" width="100%">

<tr>

<td>

<asp:DropDownList runat="server" ID="ddlLeadSource">

<asp:ListItem>Trial</asp:ListItem>

</asp:DropDownList>

</td>

</tr>

</table>

</ContentTemplate>

</telerik:RadWindow>

However, if I change the text of the list item to anything else, the VisibleOnPageLoad setting is evaluated correctly and the RadWindow is hidden.

Is this a bug, or can someone Identify something I'm doing incorrectly?

Thanks!

Copy/Paste causes line breaks to double in Chrome

Similar to this thread which has been fixed, my problem appears in Chrome when the content area style is set in OnClientLoad.

Open notepad and create a document as follows

Line 1
Line 2

Line 4

Set the font programatically within OnClientLoad (we don't want to set it in the .css as we would like the font to be customizable per-user).

function OnClientLoad(editor) {
var style = editor.get_contentArea().style;
style.fontFamily = "Tahoma";
}

Paste the text into the editor and the line breaks are doubled.

variable is set to null after jquery appendTo

I have grid on my page located in div with id "Lists":

<div id="Lists">

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

<ClientSettings>

<ClientEvents OnGridCreated="document_Grid_OnGridCreated" />

</ClientSettings>

</telerik:RadGrid>

</div>

<div id="ParentList">

</div>

when grid is created documentGrid variable is set with that grid:

<script type="text/javascript" >

var documentGrid = null;

function document_Grid_OnGridCreated(sender, args) {

documentGrid = sender;

}

</script>

to this point everything seems to be fine, I can call following code:

function updateDocumentGrid(){

documentGrid.get_masterTableView().rebind();

}

after I move Lists div inside another div with id ParentList
global variable window.documentGrid is null.

is there any way to prevent variable documentGrid from beeing set to null?

DateTimePicker align problems

I have a problem where the DateInput and DatePopupButton follows the screen if I scroll down.

I have solved the scrolling problem for DatePopupButton with:

.rcSingle .rcCalPopup
{
position:static !important;
}

But the DateInput control still scolls with the screen.

This helped me with some the problem: http://www.telerik.com/community/forums/aspnet-ajax/calendar/alignment-problem-w-raddatepicker.aspx
