Base URL

If I'm using the Editor to manage content on a different domain, is there an easy way to set the base URL for the content displayed in the Editor so that images relative to the other domain will resolve? I see that if I'm editing an entire HTML document, I have the ability to set the "Base location" in the "Page Properties." Is there a way for me to set this value programmatically?

Changing controls shown on each cell based on value of another

1. I have a grid that is created dynamically where col 1 has a dropdown box. Based on what the user selects in col 1, I should show either a textbox or dropdownlist or datepicker in col 2. How can I accomplish this?

2. Also how do I handle events when the selecteditem in col 1 changes?

The data isn't coming from a datasource, I'll be creating each row programmatically.

Thanks

External Style Sheet

I'm attempting to use the Editor to manage content from a web site with a different URL than the site the Editor is hosted in. I'd like to have the CSS styles drop-down list available styles from that external style sheet and also have that style sheet be applied to the content within the Editor so that it is displayed with the look-and-feel of the web site; however, based on some of the posts on this forum, it doesn't sound like the Editor can use an external style sheet on a different domain. Is there a simple way to programmatically read the style sheet and add it to the CSS drop-down as well as apply it to the content area?

                    rgContents.DataBind();  
        
                }

when I change page index post back will fire itemdatabound twice.
I am call rgContents.DataBind() in the rgContents_PageIndexChanged, this line code will cause that.
and when use NeedDataSource will correct, but above code why cannot work correct?

Binding to a dataset with multiple tables

I've spent some time trying to bind a dataset to a treeview where there are three tables each with a different set of columns.

Three tables; Customer, Order and LineItem

Customer [CustomerId, Name]
Order [OrderId, CustomerId, OrderReference]
LineItem [LineItemId, OrderId, ProductName, Quantity]

The theory was... Create a Dataset with apporpriate relations and bind it server side. However it doesn't seem to work - I only can see the top level and if as I specify the DataMember attribute, It doesn't even use the name property to set the text.

Any help appreciated. Is the only solution to create the nodes server side programatically and add them to the tree?

<telerik:RadTreeView ID="treeCustomer" runat="server">

<telerik:RadTreeNodeBinding Depth="0" TextField="Name" ValueField="CustomerId" DataMember="Customer" />

<telerik:RadTreeNodeBinding Depth="1" TextField="OrderReference" ValueField="OrderId" DataMember="Order" />

<telerik:RadTreeNodeBinding Depth="2" TextField="ProductName" ValueField="LineItemId" DataMember="LineItem" />

</DataBindings>

</telerik:RadTreeView>

google filtering

Hi All

I have the google filtering in the grid working as per link below. I am using usercontrols loaded view ajax as per below.
Now I have noticed with enableviewstate= false, sorting paging all work, but when I page I get two calls to code to get records from the database.

If i turn viewstate on for sorting the column name etc dispears but I only get one call to the database code.

This is a screen that clients use a lot and the extra call to the database slows things down a lot

[Solved] contentEditable on a table cell

Hi,

I'm trying to implement a custom table editor and as part of this i would like the tables content not to be editable in the editor.

I would also like the content of the editor to have a doctype.

Below is a small code sample, the problem I am having is that is is still possible to put the cursor inside the table and edit the content.

Any help would be greatly appreciated.

thanks

radcombobox working very slow on some client computers

Hello,

I have a problem with RadComboBox. The problem is that RadComboBox with the same data is working ok on some clients and very slow on other clients. We tested this problem on 6 different clients with the same browser (firefox 3.6.3) and it was working slow on 3 of 6 clients.
We are using Telerik version of dll: 2009.3.1103.35.
