RadGrid disappears on Add New

I have a very basic grid with the ability to add records directly to it. When you click Add Record, you get a blank grid until a postback. If you click the foo button, you'll see the grid comes back in add mode. I tried adding an RadAjaxPanel and a RadAjaxManager, but neither fixed the issue.

Help!

User control inside a listView

Hi !

I'm currently working on a website with asp.NET 4.0 and c#.
I need to implemente a User control in a listview. I want the listview to show a list of data from a table name Lignes (with a ligne_id as primary key) and the user control to show a list of data from a table name Blocks (with a block_id as primary key and a ligne_id as foreign key).

Here's the code I made :

My Listview :

<asp:ListView ID="ListView1" runat="server" DataKeyNames="ligne_id" DataSourceID="SqlDataSourceLigne">

<ItemTemplate>

<asp:Label ID="ligne_id" ClientIDMode="Static" runat="server" Text='<%# Eval("ligne_id") %>' />

<uc1:UC_ListeBlock ID="UC_ListeBlock1" runat="server"

Ligne_ID='<%# Eval("ligne_id") %>' />

    </ItemTemplate>

</asp:ListView>

My UserControl :

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

My user control's code Behind :

public partial class UC_ListeBlock : System.Web.UI.UserControl

{

public Int32 Ligne_ID;

private Int32 ligne_ID

{

get { return Ligne_ID; }

set { Ligne_ID = value; }

}

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

Label1.Text = ligne_ID.ToString();

}

When I execute this code, the label ligne_id from the listview has the good ligne_id from the database (so Text='<%# Eval("ligne_id") %>' is working) but the Label1 from the user control is always at 0 (so Ligne_ID='<%# Eval("ligne_id") %>' doesn't seem to work).

Do you have an idea what is wrong with my code ?

Thanks in advance for you awnser

P.S : I'm french so I'm sorry if I'm not very clear in my explanation.

Applying filter produces JavaScript error

I've got a bound column that may contain null values. If I try to use filtering on it such as "contains" or "equal", I'm getting a javascript error "Object reference not set to an instance of the object". I believe the generated logic should check for null before applying the "contains" filter. Am I doing something wrong here or is it a bug? In some posts I found that EnableLinqExpressions="false" would fix something like that. However, when I try to do that I'm getting

Server Error in '/' Application.

Cannot interpret token '?' at position 12

The grid is bound to a list of objects and is defined as follows

Grid in inline edit mode

Hi,

i am using the grid and have written a function that allow me to set all the viable rows to be edited using the inline edit method.

the grid is initially populated with 1000 rows by being bound to a data table, the grid has paging set at 25 lines per page and the user can edit all 25 items in one go, when they click update my code loops through the viable items and adds them to a new data table and this is returned to an update function.

the data table that is sent back only contain 25 rows but seems to be over a meg in size and this really kill the performance of the page when using it over a Normal ADSL connection.

can anyone tell me why the data table is so big as the data contained with in it should be a few K and i do not seem to have the same issue when the data is retrieved on load of the page.

EnableEmbeddedBaseStylesheet Odd Behavior

I have a RadMenu instance defined on a master page like this:

<telerik:RadMenu runat="server" ID="rdMenu" Skin="CustomSkin" EnableEmbeddedBaseStylesheet="false" EnableEmbeddedSkins="false" DataSourceID="menu" />

For the main page of the site (not in a subfolder), this works exactly as expected - I have a CSS file that is linked to the page which contains both a modified version of the base stylesheet plus the contents of my custom skin's CSS. The problem I'm having is any page on a subfolder seems to be having the EnableEmbeddedBaseStylesheet property ignored so I get a reference to WebResource.axd for the base which throws off all of my CSS.

Any guesses as to what would cause this property to be selectively applied when it should always be in effect? I'm on version 2012.3.1016.45.

Using ellipsis with items

I am using a RadPanelBar for a navigation menu and this will eventually be used within a frameset which can have the frame width dynamically altered.

I am using a text-overflow:ellipsis css style on the text and that works fine in keeping the text together and not wrapping midword, however the problem is that as the width of my radpanel gets smaller the text in its entirety will wrap to the next line seperating from the icons(which I have placed at the left of each radpanelitem). As far as I know I cannot use the css white-space:nowrap as that only applies to the text itself. Is there any other way to make it so the radpanelitem as a whole does not wrap?
