[Solved] Using griddata in grid under nestedview

Hi all,

I have a grid containing orders with IDs. This main grid have a nestedview in which I have a tab containing some text and another containing a new grid with the orderlines.

How can I give the information about the order id to the grid containing the orderlines. My code looks something like beneath (I have cutted out a lot of code to get a better overview of the essential code):

    
            <telerik:RadGrid ID="RgOrders" AutoGenerateColumns="false" OnNeedDataSource="RgOrders_NeedDataSource" runat="server"> 
        
                <MasterTableView ClientDataKeyNames="id"> 
        
                    <Columns> 
        
                        <telerik:GridBoundColumn DataField="OrderNumber" HeaderText="OrderNumber" UniqueName="OrderNumber" /> 
        
                        <telerik:GridBoundColumn DataField="OrderFirstName" HeaderText="OrderFirstName" UniqueName="OrderFirstName" /> 
        
                        <telerik:GridBoundColumn DataField="OrderLastName" HeaderText="OrderLastName" UniqueName="OrderLastName" /> 
        
                    </Columns> 
        
                    <NestedViewTemplate> 
        
                        <asp:Panel runat="server" ID="OrderNestedView" Visible="false">

Magical tags

Hello

One of our clients has an installation where the telerik editor is included to edit content. Now he had the issue, that the client produced some html in the design mode by using the editor functionallity. In html view the code looks like that

<table>

<><><>

</>

<tbody>

<tr>

<td>

aösdkjflöaskjdflöaksjdf

</td>

<td>

asdfasdfasdf

</td>

<td>

asdfasdfasdfsadf

</td>

</tr>

<tr>

<td>

asdfasdf

</td>

<td>

asdf

</td>

<td>

asdf

</td>

</tr>

<tr>

<td>

asdfasdf

</td>

<td>

asdf

</td>

<td>

asdf

</td>

</tr>

</tbody>

</table>

<table>

<><>

</>

<tbody>

<tr>

<td>

aösdkjflöaskjdflöaksjdf

</td>

<td>

asdfasdfasdf

</td>

<td>

asdfasdfasdfsadf

</td>

</tr>

<tr>

<td>

asdfasdf

</td>

<td>

asdf

</td>

<td>

asdf

</td>

</tr>

<tr>

<td>

asdfasdf

</td>

<td>

asdf

</td>

<td>

asdf

</td>

</tr>

</tbody>

</table>

Now, when the user switches from Design to html view and back a few times, every time, the brackets where duplicated.

I know, that the html isn't really a clean one, but i like to know if we can do something to avoid the duplication

regards
patrick

[Solved] RadEditor showing below RichHtmlField

Hello,

I'm using the "Use RadEditor to edit HTML fields" feature. This seems to be working reasonably well, except that the RadEditor is shown below the original PublishingWebControls:RichHtmlField editor. I expected this to be replaced by the RadEditor. Am I doing something wrong?

Also, it doesn't seem to be possible to use script tags in the editor (removed by sharepoint presumably), but in another site I've worked on, this does work (magically somehow). Any ideas?
I'm thinking of writing a hack that replaces script with zcript or whatever, when saving and back when rendering. How can I hook into the save / render calls?

Thanks in advance,

RadGrid + EnableViewState=False + DataReader = Invalid attempt to call FieldCount when reader is closed.

I've dumbed down my page about as much as I can.

I'm setting the DataSource of my RadGrid to the EL4 Database.ExecuteReader result.
Then I'm calling DataBind.

When I have EnableViewstate=true all works fine.

When I set EnableViewstate=false it fails (error below).

Any thoughts? Anyone seen this before?

Thanks,
Kevin

LinqToSQL Data Source with Temporary Data

I would like to use the sds:SessionDataSource that is in this demo but have it work for LinqToSQL. What is the recommended way of creating temporary data that doesnt persist back to the database when doing LinqToSQL CRUD?

Basically, I want to create a data structure that can reset itself every session so my users can fully test a web app iteratively while focusing on and approving a fully working UI before I refine the data model. Any suggestion is appreciated. :)

HTML not being updated when properties are changed

We are using Visual Studio 2008 with our web application and we are compiling it against the .NET 2.0 framework. We are still using the Telerik.Web.UI controls that are made for .NET 2.0. We've noticed that when we change the properties for the grid (add another column, change column width, modify the client settings, etc.), the change is reflected in the designer, however when you go and look at the HTML code, it never gets updated. When you run the application, the changes are not displayed either. The changes only appear when you manually modify the HTML and then run the application.

Is there something that we're doing wrong?

Thanks,

Adam

Javascript error

Hi,

I am having an issue with a content page that gives a javascript error every time I click on a radtabstrip tab the code is below

<%

@ Register Assembly="Telerik.Web.UI, Version=2009.1.527.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"

</telerik:RadPageView>

<telerik:RadPageView ID="PageChangePassword" runat="server">

</telerik:RadPageView>

</telerik:RadMultiPage>

the issue seems to be if there is a radcombobox within a radpageview,

the javascript error is on the following line.

Sys.WebForms.PageRequestManager.getInstance()._destroyTree(_3c);

I am running VS 2010, IE8 on Server 2008, I have attempted to recreate the page serveral times and the error occurs on every new page.

Regards
