Column hide / show does not resize correctly

Hi I am having some issue when using the option for showing / hiding column via the context menu in the header of a grid.

My grid is made so it fits on the width of the screens we used. We have a column hidden by default. When i decide to show the hidden column, the grid does not resize and instead it is the columns which are resized. I would like instead that the columns stay at the width I already set in my page with the property "HeaderStyle-Width" and that a scrollbar appears at the bottom of my grid.

Is it possible to do that ?

Thanks

Guillaume

Disable Dragging Handles

Is it possible to disable the dragging handles on an appointment entry? I'm not trying to disable editing completely (the context menu needs to remain enabled), just prevent a user from dragging the entry to extend the time.

Client Side Programming

I am still exploring the Spreadsheet control and I can see where it would be a useful tool. I am able to get cell values using JavaScript but I don't see a way to change the values. Also, I would like to see a cell onChange event that would allow me to format the font color if the value changes.

We are using similar functionality using your grid control on a screen. The spreadsheet control might be better suited for this screen if I can add this functionality. Is this available? If so, can you provide example code? If not, are you planning to add these to the Spreadsheet control?

Hi Telerik Team,

We are using Telerik AJAX UI control version "2015.3.930.45" in our project. We are using Telerik Image editor in our application and we are facing issue with the eps files to display in Telerik Image editor.

<telerik:RadImageEditor ID="TelerikRadImageEditor" runat="server" ImageUrl="https://<servername>/<folderName>/<fileName>.<extension>" >
</telerik:RadImageEditor>

Please help us out to resolve this problem.

RadGrid's NeedDataSource Firing Another Postback?

I have a page structure like this:

-- Master Page
    -- Page
        -- User Control
            -- RadGrid

In the user control the component structure is like this:

-- <div>
    -- <ajax:ModalPopupExtender>
        -- <asp:Panel>
            -- <telerik:RadGrid>

In my user control's Page_Load method, I have something like:

protected void Page_Load(object sender, EventArgs e)

{

LinkButton myLinButton = myMasterTemplate.MyButton;

myLinkButton.Click += myLinkButton_Click;

if (Page.IsPostBack)

myGrid.NeedDataSource += myGrid_NeedDataSource

...(more code)

}

What happens is when I click on the link button the modal window will show up which contains the grid. It works fine except the user control's Page_Load event fires twice. If I comment out the line "myGrid.NeedDataSource += myGrid_NeedDataSource " then it's fine but of course I can't do that. This leads me to believe, internally, NeedDataSource is causing another postback. Is this correct? If so, is there any way to prevent this from happening?

Thanks.
