RadColor picker object is null

Hi,

I am able to obtain the RadcolorPicker object on in the following case:

serverside code(aspx.cs)

protected void Page_Load(object sender, EventArgs e)

{

dropdownList1.Attributes.Add("onchange", "javascript:clddIndicesList_onchange();");

}

Clientside code:(aspx)

function clddIndicesList_onchange()

{

radColorPicker.set_visible(true);

}

but RadColorPicker object will be 'null' in the following cases

1) <body onload="clddIndicesList_onchange()">

2) End of the aspx page <script language="javascript" type="text/javascript">clddIndicesList_onchange();</script>

Please let me know the solution for this?

EVERYBODY - Add DropDownFloatDir property to the TODO list

Hi all,
please show your support if you see the necesity in the above property, which allows you to choose the dropdown list floating direction
(left or right), and by this aligning it's right border to the input cell right border or its left border to the input cell left border.

Telerik said :
"Currently RadComboBox does not support this functionailty out-of-the-box. If the demand for it increases in the future we may consider incorporating it in the control."

see : http://www.telerik.com/community/forums/aspnet-ajax/combobox/combobox-drop-down-location.aspx#718149

Thank you,

Strange Hide/Show Filtering Behavior

Hello,

I implemented the code similar to the demo at http://demos.telerik.com/aspnet-ajax/Grid/Examples/GeneralFeatures/Filtering/DefaultCS.aspx in regards to the Radio buttons to hide and show filtering. The problem is, however, that instead of hiding and showing the filtering it is hiding and showing the header columns. Any idea as to why this could be?

Paste from Word not working after paste from IE edit menu

Hello.

I'm using Telerik RadEditor 7.3.2.0 and I have the following problem.

I have a text in MS Word with TimeRoman 11 font. I have initialized RadEditor with

Editor.StripFormattingOnPaste =

EditorStripFormattingOptions.MSWordRemoveAll

and the unique font is Arial 14.

When I copy the text in from MS-Word and I paste it into the Editor with the Paste from Word button, it works fine. The text is converted to Arial 14.
Right after that I paste using the IE Edit / Paste menu item and the text is appended to the previous block but with font TimesRoman 11.
Then I paste again with the Paste from Word button and the text is pasted as TimesRoman instead of Arial.

It seems that after a paste from outside the editor (IE menu item), the Paste from Word does not clear the font settings.

1. How can we avoid this situation ?
2. Is it a way to apply the FormattingOptions even if the paste action is coming from the IE menu ?

Thanks for your help.
Regards
Augusto

set_cancel in OnRowClick event

Hi,

I'm trying to use the set_cancel() function in the client side OnRowClick event and it said the function does no exist.

The help file says "Can Be Cancelled: Yes, meaningful when setting ClientSettings -> EnablePostBackOnRowClick to true" and even has sample code demonstrating it. I do have enablepostbackonrowclick set to true but the method cannot be found.

eventArgs is returning an object and I can successfully get the data grid item from it.

Any ideas?

Thanks,
Vandara Peou

DockedPaneId fails if Pane is hidden

I am writing to determine if the behavior I'm seeing is intended functionality or if I've made a simple mistake. I have configured the Telerik controls on my my master page as follows:

            </telerik:RadSplitter>         

I am checking for a cookie on the user's computer and if it doesn't exist then I'm expanding the ParamsSlidingPane RadSlidingPane to fill the browser window, pin it, and then disallow unpinning so that they are forced to use the submit button to validate the selections made on the RadSlidingPane and then write them to a cookie. I set the session variable for WindowWidth using another page with some Javascript. As that isn't pertinent to this, I'm not including it. Here is the server-side code for the above described:

                    // Check user's cookies for picker values         
            HttpCookie Parameters = Request.Cookies["Parameters"];         
            // If there is no cookie...         
            if (Parameters == null)         
            {         
                // ...slide the pickers pane to full screen width...         
                ParamsSlidingPane.Width = Unit.Pixel(int.Parse(Session["WindowWidth"].ToString()) - (int)ParamsPane.Width.Value - 2);         
                ParamsSlidingZone.ExpandedPaneId = ParamsSlidingPane.ClientID;         
                // ...pin it...         
                ParamsSlidingZone.DockedPaneId = ParamsSlidingPane.ClientID;         
                // ...block unpinning so they have to use the submit button...         
                ParamsSlidingPane.OnClientBeforeUndock = "BlockUndock";         
                // ...hide the right pane...         
                RightPane.Visible = false;         
                // ...and show a message         
                noCookie.Visible = true;         
            }         
                     

The code I'm using to prevent unpinning of the ParamsSlidingPane is simple and provided mainly for anyone else, like myself, who has been puzzling over this but also for completeness.

                    <script type="text/javascript">           
                function BlockUndock(sender, Args)           
                {           
                    Args.set_cancel(true);           
                }         
            </script>         

That described, the behavior is that if I hide the RightPane RadPane, then the ParamsSlidingPane RadSlidingPane won't pin. If I comment out the code to hide the RightPane RadPane, then it pins fine but that causes scroll bars to occur and the contents of the RightPane, which are invalid until the cookie is set, can be seen if the user scrolls over. If I comment out the RightSide RadSplitter, then the pinning works fine but I still get scroll bars with no contents, only the frame of the RadSplitter.

The goal here is simple -- show the parameters pane if there is no cookie and don't let the user see anything but the parameters pane until he sets the parameters. Any guidance would be appreciated.

Unable to ajaxify the Grid

I create a small application in server side which performs same function like EnableHeaderContextMenu. And also i save the selected column name in Database, so that the next time the grid loads with the column which is saved in the database.Everything is done fine without ajax. But when I tried for ajax the column is not updated in the grid. Please help me in this reqard. I am using Master page for ajax.
