Hi,

About multiline radtextbox : Have you experienced some scenario where RadTextBox1.text server side is more than 100 character long even if MaxLenght = 100 ?

I can't reproduced myself the problem but I had a couple of 'string or binary data would be truncated' while inserting in a nvarchar(100) sql server field.

I'm not using multiline very often and forgot to check server side the lenght of the text before inserting.

Anyway, I'm thinking about an old browser usage (IE6 ?) ?

What do you think ?

EDIT : using last telerik dll

Thanks
Arnaud

Multiple Windows Incorrectly Sharing Passed In Variable

Hello,

I am implementing RadWindow in a user control that will pop up context sensitive help whenever the user clicks an icon. The intention is that I will drop the user control anywhere on a page that requires it (i.e. multiple instances on the one page).

I have set up a hidden field on the user control so that each time it is dropped onto the page I can set the value of the field which is then used by the control to determine which help data to load.

The problem is that it seems the window the control uses is shared across all instances and it is unable to store the value independent of one another (therefore the same help text appears each time regardless of which help control is clicked).

Here is my Help Control code:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Help.ascx.cs" Inherits="Controls_Generic_Help" %>

<script type="text/javascript">

function openHelpWindow(sender, args) {

var radWindow = $find("<%=radWindow1.ClientID%>");

var docId = $get("<%= documentIdField.ClientID%>").value;

radWindow.setUrl("help.aspx?Id=" + docId);

radWindow.show();

}

</script>

<telerik:RadButton id="helpButton" runat="server" autopostback="false" Width="16" Height="16" onclientclicked="openHelpWindow">

<Image EnableImageButton="true" ImageUrl="~/images/icon-help.png" IsBackgroundImage="false" />

</telerik:RadButton>

<telerik:radwindow id="radWindow1" runat="server" Width="600px" Height="600px" VisibleTitlebar="false"></telerik:radwindow>

<asp:HiddenField runat="server" ID="documentIdField" />

Then all I do on the page where the control is dropped is set the hidden field value:

Help1.HelpDocName = "HelpQuickLinksNavigator";

Help2.HelpDocName = "HelpActivityFeed";

However all that happens is that the first value only is used each time the window is opened.

Thoughts?

[Solved] detail Table ID having the parent grid

As i click on a checkbox (template column) in a row of the main grid an event is raised and
a client-side function is called.

Inside this function I need to do something on its detail table, I don't have, and I need it, the ID of that Detail Table
I did like this:

var grid = $find(gridClientID);
var childGridID = grid.get_detailTables()[ROW].get_dataItems()[0].get_id()

ROW is the index of the main grid row to which the checkbox belongs.

But...
grid.get_detailTables()[index].get_dataItems()[0].get_id()
index actually refer to the index of the expanded ones, so if click on the first row (ROW=0) and first row is not expanded and the second row is expanded the action takes place on the second row (ROW=1) because is the first expanded

How do I know
1) detail Table ID having the parent grid?
2) if it's not expanded can I work on it?

Thank you

Rebind Detail Table Client Side

I have found several old posts where people are asking how to do this, and also mention that it may be addressed in an upcoming release. Just wondering if there is a method of rebinding the detail table of a RadGrid from the client side ?

Thanks

[Solved] RadGrid PDF Export - Image Size Issue

Hi guys,

Loving the PDF export functionality so far. Although I'm struggling with an issue with image size when exported to PDF.

My radgrid displays some jpg and gif images which are quite large, so I'm resizing them dynamically with OnItemDataBound.
This all works fine on the page, but when I export the radgrid to PDF, the images seem to lose their dimensions i.e. they display at their original size in the PDF.

Is there a way to resize them for PDF export? I've been using the ItemCreated event to modify cell sizes etc, but can't work out how to do the same with images.

Thanks,
Andrew

Scroll to item programatically

Hi, I have a RadGrid with scrolling capability. The user can use a search box to enter a reference for a row, and if it's found I need to automatically scroll to that row and select it.

I have the selection working, but it doesn't scroll down automatically to it - is there a way I can do this?

Add new record triggers onbeforeload

Hi,

For some reason when I press the + button on the RadGrid it doesnt trigger onbeforeload. However when I click the "Add new record" LinkButton is does, which is not desired. Below i have attached sample code to reproduce this behavior. Is there valid Telerik solution to this problem, other then the one I have provided at the end of this post?

As i mentioned before, I have found a workaround by doing the following:

<ClientEvents OnCommand="RaiseCommand" />

where the function itself has no code:

function RaiseCommand(sender, eventArgs) {

//By adding this, it prevents onbeforeunload from firing as a redirect,

//When Add New Record is clicked insead of + button.

}

Thanks,
Aash.
