Varible height for the dynamically created RadDoc

Hello,

I am creating raddocs dynamically. I do have dynamic radzones. Also I wish to create raddocs with varible height dynamically. Its height should get varied as per the contents inside it.

If I do not set the height of raddoc while creating it dynamically then it set to some default value and displayes scrollbar.

Automatic Operations ObjectContainerDataSource

Hi,

I have never posted before, I hope this is the correct place. My markup is below. When I click the edit button on a row and make a change in the Edit form, no update events are raised on the datasource . I have copied the sample several times from the website but I still cannot get my events wired up properly. I am using WCSF and am quite familiar with this framework. The datasource seems to work fine if I use an asp.net GridView. Any help would be appreciated.
Thanks

how to update UI when deleting grid row?

I have a RadGrid with a GridButtonColumn that has CommandName="Delete". When I click this button, the events for ItemCommand and DeleteCommand both fire. In the ItemCommandEvent I run some code to delete the record from the database.

The record gets deleted from the DB, but the row still exists on the UI. I've tried calling the Rebind() and DataBind() methods on my radgrid, but that makes no difference.

I've also tried using a GridClientDeleteColumn instead of the GridButtonColumn. This causes the row to disappear from the UI, but no server-side events fire, so I cannot actually delete the data from the DB.

RadUploadProgress 2009.1.527.35 Stopped Working Recently

For some unknown reason, my RadUpload 2009.1.527.35 (ASPNET AJAX Q1 2009) has malfanctioned both in my production and development servers on an application that has been online for years (with regular updates but nothing file related recently)

I have re-downloaded and installed the .MSI on my local machine and the live Upload samples are not working correctly either. The files (2MB - 99MB) upload fine, but there is no progress indicators.

If anyone else is recently having this problem, speak up so I know I am not crazy.

Local Machine: Win7, Asp.net 3.5, VS 2008 Web Server
Production: Win Server 2003 , Asp.net 2.0, IIS 6

Multiline RadTextBox removes the first newline if it is not preceeded by other text

Hello,

If I set the text of a RadTextBox to something like the following:

"\r\n\r\n\r\nSome text\r\n\r\n\r\nSome more text"

I believe there should be three empty lines and then on the fourth, "Some text". This is how the standard asp.net textbox works when in multiline mode.

If I modify the text to:
"a\r\n\r\n\r\nSome text\r\n\r\n\r\nSome more text"
Then both textboxes behave the same.

The problem I have is that after a postback, if I intended there to be three empty lines before the text, only two are displayed on the page. Thus, only two are returned in the Viewstate. Upon a second postback, only one line exists in the Viewstate and so forth until non-space characters are all that is left at the beginning.

I have mocked up a simple page showing this issue. After each click of the 'Postback' button another line is removed. The Asp.Net textbox works just fine. Is there a simple way to fix this?

<body>

<form id="form1" runat="server">

<div>

<telerik:RadScriptManager ID="ScriptManager1" runat="server"></telerik:RadScriptManager>

<telerik:RadTextBox ID="txtMessage" runat="server" TextMode="MultiLine" Rows="10" Columns="200"/>

<asp:TextBox ID="txtASPMessage" runat="server" TextMode="MultiLine" Rows="10" Columns="200"></asp:TextBox>

<br />

<asp:Button ID="btnPost" runat="server" onclick="btnPost_Click" Text="PostBack" />

</div>

</form>

</body>

    protected void Page_Init(object sender, EventArgs e)
    {
        txtMessage.Text = "\r\n\r\n\r\nSome text\r\n\r\n\r\nSome more text";
        txtASPMessage.Text = "\r\n\r\n\r\nSome text\r\n\r\n\r\nSome more text";
    }

    protected void btnPost_Click(object sender, EventArgs e)
    {
    }

Thank you in advance!

radsplitter 100% height on Chrome with AjaxUpdatedControl

Hi there,

I have a radsplitter on 100% height. Everything seems to be working fine until I attach a AjaxUpdatedControl to the radsplitter.

Once I attach the AjaxUpdatedControl, the height of the radsplitter seems to be fixed at a particular height. You can refer to the 2 files to see the difference.

Below are my code

Btw, this only happens in Chrome. It works fine in IE8 and Opera. Haven't tested on FF.

Key cannot be null. Parameter name: key

Hi Sir,
i am binding my RadGrid with ORM like this

oadsSource.ObjectContextProvider = "RadControlApplication.EntitiesModel, RadControlApplication";
        oadsSource.TypeName = "RadControlApplication.TblCustomer";
        oadsSource.EnableDelete = false;
        oadsSource.EnableUpdate = false;
        oadsSource.EnableInsert = false;
        oadsSource.StoreOriginalValuesInViewState = false;
        rdGridCustomer.DataSourceID = "oadsSource";

here oadsSource is the object of my OpenAccessDataSource control, that i put in my aspx page.
and RadGrid is bound properly.

i am setting the properties of my radGrid for Excel Exporting as
        rdGridCustomer.ExportSettings.FileName = "MyDataFile";
        rdGridCustomer.ExportSettings.ExportOnlyData = true;
        rdGridCustomer.ExportSettings.IgnorePaging = false;
        rdGridCustomer.ExportSettings.OpenInNewWindow = true;
        rdGridCustomer.ExportSettings.Excel.FileExtension = "xls";
        rdGridCustomer.ExportSettings.Excel.Format = Telerik.Web.UI.GridExcelExportFormat.ExcelML;

now on button click event i am writing this code

this.rdGridCustomer.MasterTableView.ExportToExcel();
but i am facing the error
Key cannot be null. Parameter name: key
But if i bind my RadGrid with other data source like SQLDATASOURCE then its work fine.no error occurs.
and if i use other datasource like datatable then also its work fine for export in ExcelML format.
But i have to use ORM actuly.
I need solution please.
Thanks very much

Progress bar not fluid

Good morning,

We have a page from which users can upload big files. We are using asyncUpload control to achieve this.

In development enviroment, progress bar moves in a fluent way but, when in production, progress bar only makes 3 steps (not always the same, but very strange, because first step always starts over the 30%).

May we configure something to make this progress indicator more fluid?

Thank you very much
