On closing the RadSpell dialog box I get the following javascript error: "Error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus.

Hello,

I am observing a typical behavior on closing the RadSpell dialog box.

Steps to replicate the issue:

Open the RadSpell dialog box.
Ensure that the text box that it is trying to spell check has at least one invalid text entry (as per the dictionary used).
Now, close the spell check dialog box before it shows the valid suggestions for the incorrect entry (as per the dictionary used).
The browser would then show the following java script error: "Error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."

I know why this is happening. Reason is simple: The HTML element that the RadSpell is trying to bring focus is no more visible because I closed the dialog box. Please let me know if I can tweak something somewhere to avoid the above thing from happening.

I am using RadControls Q3 2008. I have tried the above scenario on the IE8 browser.

Thanks.

Export stops working after column sort

Hi,

I'm using version 2010.2.826.40.

My RadGrid exports work fine until I do a column sort or group. Then, when trying to export, the entire grid simply re-displays itself in the browser.

Here's my code.

Thanks much,
Dan Cogswell

Does Upgrading from office 2003 to 2007 affects RadEditor v:5.6.4.0 and RadSpell.dll v:2.6.1.0?

Hi,

I have a question regarding to the possibility of Microsoft office upgrade effects on RADcontrol?

We are using the following dll for our editor.
- RadEditor Version = 5.6.4.0
- RadSpell.dll Version = 2.6.1.0
We would like to upgrade our Microsoft office from 2003 to 2007.
Does it affect RADContorols?

Should we also retest our RADControl after upgrade or they are not using Microsoft office dlls?

Thank you in adavance,

Object Doesn't Support this Property or Method

I'm trying to show/hide a loading panel based on what control made the request. My javascript is as follows:

var objLoadingPanel = "";

var objPageRequestManager = Sys.WebForms.PageRequestManager.getInstance();

objPageRequestManager.add_initializeRequest(RequestInitializing);

objPageRequestManager.add_endRequest(RequestEnding);

function RequestInitializing(sender, eventArgs) {

objLoadingPanel = $find("<%=lpLoadingPanel.ClientID%>");

if (eventArgs.get_eventTarget() == "<%=btnRefresh_SpendingStatus.ClientID%>") objUpdatedControl = "<%=lblChart_Status.ClientID%>";

//show the loading panel over the updated control

objLoadingPanel.show(objUpdatedControl);

//objLoadingPanel.show("<%=lblChart_Status.ClientID%>");

}

function RequestEnding(sender, eventArgs) {

if (objLoadingPanel) objLoadingPanel.hide(objUpdatedControl);

objUpdatedControl = null;

objLoadingPanel = null;

}

However, when I click the "btnRefresh_SpendingStatus" button, I get the following error: "Object doesn't support this property or method". Am I missing something? Thanks.

Trying to access TextBox in a RadGrind and pass it to RadWindow

Hi,

I am trying to access the text box in a radgrid and pass the values of the selected row in the grid with the new value in the textbox to a radwindow which is opened when a button in the same row is clicked.

I am using the following code

aspx:
function ShowDispatchNote(rowIndex, MediaID, ReferenceText) {
   var grid = $find("<%= rgBookoutMedia.ClientID %>");
   var firstDataItem = $find("<%=rgBookoutMedia.ClientID %>").get_masterTableView().get_dataItems()[rowIndex];
   var MediaID = firstDataItem.getDataKeyValue("MediaID");
   var masterTable = grid.get_masterTableView();
   for (var i = 0; i < masterTable.get_dataItems().length; i++) {
   // to access the textbox in each row
   var txtbx = masterTable.get_dataItems()[i].findElement("rtbReference");
   // set alert
   }
   window.radopen("DispatchNote.aspx?MediaID=" + MediaID + "&ReferenceText=" + txtbx.Text, "RadWindow1");
   return false;
   }

cs:
if (e.Item is GridDataItem)
   {
   GridDataItem dataItem = rgBookoutMedia.NamingContainer as GridDataItem;
   Button btnConfirm = (Button)e.Item.FindControl("btnConfirm");
   RadTextBox rtbReference = (RadTextBox)e.Item.FindControl("rtbReference");
   btnConfirm.Attributes["onclick"] = String.Format("return ShowDispatchNote('{0}','{1}');", e.Item.ItemIndex, e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["MediaID"], rtbReference.Text);
   }

I am able to get the value of MediaID as I have specified it as DataKeyNames in the MasterTableView. The other query string ReferenceText shows up as undefined always. How do I get the value of the textbox with new values in the client side before opening the rad window.

The example in http://www.telerik.com/community/code-library/aspnet-ajax/grid/accessing-server-controls-in-a-grid-template-on-the-client.aspx doesn't satisfy my criteria. Can anyone show me a code sample on how to pass the new textbox value to the radwindow.

Thanks

RadSplitter LiveResize causing performance issues. Looking for workaround.

Hi Telerik,

So, I am creating a web portal and it is mainly composed of dynamically created controls. There is a RadSplitter which holds panes which are resizable through the use of the RadSplitBar.

The issue is this: If I have LiveResize turned on -- the user grabs aholds of the RadSplitBar and drags it around. This cause's the client-side OnClientResized event to fire...a lot, I believe. Yet, it looks all normal. No lag or anything after the resize finishes and nothing seems to be hanging. Then, I dynamically create a new control on the page and throw up a loading icon as it generates. The amount of movement of the RadSplitBar seems to be correlated to the amount of time it takes the control to appear on the screen. If LiveResize is off, I see no real issues. If I move the RadSplitBar only a little then the control is created in ~5 seconds. If I grab the RadSplitBar and drag around wildly -- the control never seems to create and the program hangs with a loading panel.

I'm looking for a solution to this as our web dashboard is fairly interactive and it would be nice to see the changes live.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server" >

<script type="text/javascript">

function OnClientResized(pane, args) {

var context = new Object();

var paneIDandHeightandWidth = pane.get_id() + ',' + pane.get_height() + ',' + pane.get_width();

//Context is just thrown away.

CallSetDimensions(paneIDandHeightandWidth, context);

}

function CallbackOnSucceeded(result, context) {

//Logging

}

function CallbackOnFailed(result, context) {

//Logging

}

</script>

</telerik:RadCodeBlock>

The dynamically created RadPane's set their OnClientResized event to this OnClientResized function.

Server-side code:

protected void Page_Load(object sender, EventArgs e)

{

RegisterCallBackReference();

}

private void RegisterCallBackReference()

{

String callBack = Page.ClientScript.GetCallbackEventReference(this, "arg", "CallbackOnSucceeded", "context", "CallbackOnFailed", true);

String clientFunction = "function CallSetDimensions(arg, context){ " + callBack + "; }";

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Call To Server", clientFunction, true);

}

#region ICallbackEventHandler Members

String returnValue;

string ICallbackEventHandler.GetCallbackResult()

{

return returnValue;

}

void ICallbackEventHandler.RaiseCallbackEvent(string eventArgument)

{

bool result = SetDimensions(eventArgument);

if (result)

{

returnValue = "Success.";

}

else

{

returnValue = "Failure.";

}

#endregion

private bool SetDimensions(string args)

{

bool saveSuccessful = false;

string[] paneIDandHeightandWidth = args.Split(',');

string paneID = paneIDandHeightandWidth[0];

int paneHeight = 0;

int.TryParse(paneIDandHeightandWidth[1], out paneHeight);

int paneWidth = 0;

int.TryParse(paneIDandHeightandWidth[2], out paneWidth);

RadPane pane = Utilities.FindControlRecursive(Page, paneID) as RadPane;

if (!object.Equals(pane, null))

{

saveSuccessful = true;

RadPaneSetting paneSetting = RadPaneSetting.GetSettings(pane);

pane.Height = new Unit(paneHeight, UnitType.Pixel);

pane.Width = new Unit(paneWidth, UnitType.Pixel);

controlSave.SavePane(pane);

}

return saveSuccessful;

}

Sorry this code isn't exactly..standard. I need to be able to call SavePane after updating a pane's properties so that Session is aware of the updates. Then, when the page reinitializes I get pane's that maintain their resized-ness.

Does this all make sense? Is there anything I can do here? Something like... detect that more re-sizes have occurred (e.g. the user hasn't let go of the RadSplitBar yet) and only call my event after all the resizing is done? I only need to save the pane state at the end of all the movement.

Cannot find RadUpload.Net2.dll in 2010 Q1

Hi to all.

I'm trying to use the RadProgressArea, but I get an error alert message (attached screen).

I'm going to this help topic http://www.telerik.com/help/aspnet/upload/raduploadprogresshandler.html and I try to follow the instructions, but I'm still having errors, then in the web config (attached screen again). I have the 2010 Q1 version installed of ASP.NET AJAX controls and I only have the Telerik.Web.UI.dll and the Telerik.Web.Design.dll files.

What I have to do?

Thanks in advance and happy new year.
