column width is changing

I have a grid that resizes the column width after the page is rendered so there is a gray area (blank space) to the right of the last column.

It is wrapping the columns data.

I would like the column width to fill in the grid width. its fine if it still wraps but I would like to get rid of the gray area. I do not see any column width settings?

Work with app_theme don't work. Please help.

Hi,

We build a web application with only the Telerik controls!
For the moment we manage the skin via the web.config.
So all controls in the pages are without skin attribute.
Now we want to have different skins who are loaded when a customer is logged in the application.

I make a new skin with the Style Builder ( very nice tool ;-) )
I upload this new skin in my project like an App_Themes.

I put in my webconfig the following code:

<

add key="Telerik.EnableEmbeddedSkins" value="false" />

<

add key="Telerik.EnableEmbeddedBaseStylesheet" value="false" />

<

add key="Telerik.Skin" value="MySkin" />

I punt also on the page the theme MySkin.

I can see that all css are loaded but the controls are rendered without style.

I don't know if this approche is the best way for what i want to do.
Also set the information in the web.config is not a solution because the skin is different by customer (I would like to put this in the cs of the master page).

I found a lot of informations, documentations, video etc ... but nothing is very clear for my problem.
I try also differents approche but nothing work.

I'm using the telerik control version 2009.3.1103.20
Is it a problem for the style builder? do i need to migrate to the laste version of telerik?

Could you please help me with this.

In advance thanks,

Edwin.

Client side in-place add/edit/delete

We use client-side data binding extensively for our "read only" grids and it works great. However, I now have a scenario where I would like to use the RadGrid to edit data.

Is there a way to bind the data on the client side and then put all rows into "edit" mode? I tried the "editAllItems" method on the master tableview but it doesn't actually put the rows into edit mode, it just does a postback telling the grid to do the work on the server.

I want to be able to add, edit (in place) and delete rows on the client without ever generating a postback. All rows should *always* be in edit mode. Is it possible?

Hierarchy grid how to access the parent key??

I have a rad grid where the 2nd level of the hierachy has a tab control with two page views each of which has a radgrid on it. I want to load the child grids server side manually (i.e. doing the read and binding myself). Currently I'm trying to do this in the Item_Command event. Is this the right event? If so, how can I determine the key of the master grid row that is being expanded? If not, what is the correct event to be able to do this? I need the key in order to load the grids on the tabs.

Thanks

Chris

Send ItemsPerRequest to RadComboBoxContext in WebServiceMethod

Hi,

I am using RadComboBox with WebServiceMethod. Why is it so that RadComboBoxContext doesn't contain ItemsPerRequest property.

<telerik:RadComboBox ItemsPerRequest="20" ..../>

I have also tried to manually add the ItemsPerRequest to the context (IDictionary) on the event OnClientItemsRequesting but i can't seem to find the propery ItemsPerRequest from javascript.

example code:

<telerik:RadComboBox ItemsPerRequest="20" OnClientItemsRequesting="onClientItemsRequesting" ..../>

//javascript
function onClientItemsRequesting(sender, eventArgs) {

var context = eventArgs.get_context();

context["FilterString"] = eventArgs.get_text();

context["ItemsPerRequest"] = sender.ItemsPerRequest; // ? where can i find the property
}
