[Comments in RadEditor] Changing RadEditUser/Author attribute

Hi,

I am now integrating RadEditor into my collaborative appliaction. I found the feature "commenting in RadEditor" interesting as users are able to make comments on the contents. However, I just wonder how to change the RadEditorUser/Author attribute because everytime a user makes a comment, Radeditor would set the author as "RadEditorUser". This causes confusion as users cannot distingish their comments with those made by others.

Thanks
Nelson

Accessing child programatically - master/detail.

I am trying to automatically expand to detail level the newly inserted master record (which works)
and then auto put the child into insert mode which I cant seem to get working.

It throws the 'index out of bounds' error on the :

Dim tableView As GridTableView = DirectCast(item.ChildItem.NestedTableViews(0), GridTableView)
tableView.IsItemInserted = True

Any advice appreciated.
Thanks in advance.

RadNumericTextbox

HI,

This is with reference to the below thread

http://www.telerik.com/community/forums/aspnet/input/change-max-value-of-radnumerictextbox.aspx

I know that RadNumericTextbox has a limitation of 2^46 but is it possible to turn-off the automatic rounding to the maximum value allowed. I don't want the user to automatically be rounded to the maxvalue if the entered value is larger. Instead, I want to signal the user about the error, and ask him/her to retype the value.

can anyone please help me in this

Specified argument was out of the range of valid values - Solution Post.

I ran into this error and I wanted to post my work around to it. I was trying to add a popup warning to an existing edit button that kicked off an edit for a grid. The error I got is below.

Specified argument was out of the range of valid values.

Parameter name: ItemHierarchicalIndex

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Parameter name: ItemHierarchicalIndex

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

[ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Parameter name: ItemHierarchicalIndex]

Telerik.Web.UI.GridDataItemCollection.get_Item(String hierarchicalIndex) +113

Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument) +3642

System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +29

System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2981

What caused this error was the javascript I added to fire the grid_ItemCommand after the popup. It was firing off code inside the RadGrid Control before it ever got to my codebehind and this code was having the error.

Bad Code

<Telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script language="javascript" type="text/javascript">

function confirmEdit() {

// This function prompts the user if they want to edit (Y/N).

<% If ShowPopup Then %>

radconfirm("The date selected is a prior period date, are you sure you want to edit the data for the date shown?", confirmCallBackFnEdit, 330, 100, null, 'Edit Receipt Noms (Y/N)');

<% Else %>

var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

masterTable.fireCommand("Edit", "");

<% End If %>

}

function confirmCallBackFnEdit(arg) {

if (arg) {

var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

masterTable.fireCommand("Edit", "");

}

</script>

</Telerik:RadScriptBlock>

To fix this error I renamed the CommandName I was looking for in the code behind Grid_ItemCommand from Edit to EditAll, changed the commandname on the button in HTML to EditAll and I changed the javascript to call EditAll. This bypassed the code inside the RadGrid control causing the error.

Good Code

<Telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script language="javascript" type="text/javascript">

function confirmEdit() {

// This function prompts the user if they want to edit (Y/N).

<% If ShowPopup Then %>

radconfirm("The date selected is a prior period date, are you sure you want to edit the data for the date shown?", confirmCallBackFnEdit, 330, 100, null, 'Edit Receipt Noms (Y/N)');

<% Else %>

var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

masterTable.fireCommand("EditAll", "");

<% End If %>

}

function confirmCallBackFnEdit(arg) {

if (arg) {

var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

masterTable.fireCommand("EditAll", "");

}

</script>

</Telerik:RadScriptBlock>

It looks like a button CommandName of Edit should be treated like a reserved word until Telerik fixes this issue.

RadAlert on top disabling application

Hello,

some days before I faced a strange behavior. I tried to show a radAlert window, from a modal radWindow, on top of all windows, so I set its z-index clientside like this:

_radalert.get_popupElement().style.zIndex = 100000;

The problem was that the radAlert was shown on top, but the gray-color panel was placed behind the radWindow, so the radWindow remained active, not disabled.

Finally I found a solution, setting this property, too:

_radalert.get_popupElement().style.zIndex = 100001;
_radalert._modalExtender._backgroundElement.style.zIndex = 100000;

What I would like to know is if there is a public property or a 'get' method to access the private object "_modalExtender"

Thanks in advance.

RadGrid ItemCommand not firing with fireCommand

Hello,

I use RadGrid and have javascript function that calls fireCommand for adding new rows. It works only when I the grid is not empty. When the gird havs 0 rows, it still fires Page_Load, but not the event handler for ItemCommand event. It used to work before the last 2 updates.

See the example below:

Main.aspx:
