I'd like to use the grid like Excel.

1. As soon as the user selects a datacell it goes into edit mode (not using F2 or key stroke to enter edit mode). Is this possible?
2. When the user press Enter key, move to next datacell (and go in to Edit mode of course)
3. When in datacell and end of text and user press Right arrow key, move to next datacell (and go in to Edit mode of course)
4. When in datacell and beginning of text and the user press Left arrow key, move to previous datacell (and go in to Edit mode of course)

Everything to get the grid to act as Excel.

Changing current row and mainaining multiselection

In my GridView the user selects a number of rows, and then asks to do some processing based on each of the selected rows, one by one.

The rows are typically selected by "normal" multirow selection, by pressing the shift or ctrl key and clicking the rows/range of rows in question. The last clicked row is then selected, and the arrow to the left is on this row, while the others are marked with blue.

When the processing begins the first (topmost) row and then the rest in sequence. I would like the arrow to follow the row in progress, but by setting CurrentRow, the "multiselection" is cleared, and only the CurrentRow is marked with blue.

Is there a way to programatically move the arrow to the left without clearing the "multiselection"?

RadButtonElements containing links to URLs

Is there an example of this (VB or C#) found anywhere on this site? I seem to be coming up short. I've been learning .net / vb for the past year, but have not had the privilege of coding such an object to date.

We're looking to deploy an organizational-wide (internal) radRibbonForm that would basically be deployed as a floating toolbar for users to gain quick access to internal resources.

The RibbonTab is a great high level way for user to navigate topic, and then within each tab, the RibbonBarGroup contains relavent DropDownButtons, which of course contain ButtonElements...

When I click the buttonElement, I get a 'Win32Exception was unhandled' error.

Here's an example of a particular Button Element's code:

    
            Imports System.Web  
        
            Imports Telerik.WinControls.UI  
        
            Partial Public Class RadRibbonForm1  
        
                Private Sub rbeD1CPT_Click(ByVal sender As Object, ByVal e As EventArgs) Handles rbeD1CPT.Click  
        
                    System.Diagnostics.Process.Start("iexplorer.exe", "http://www.google.com")  
        
                End Sub 
        
                Public Sub buttonClickEvent(ByVal sender As Object, ByVal e As EventArgs) Handles rbeD1CPT.Click  
        
                    Dim rbeD1CPT As RadButtonElement = TryCast(sender, RadButtonElement)  
        
                    System.Diagnostics.Process.Start("iexplorer.exe", DirectCast(rbeD1CPT.Tag, String))  
        
                End Sub 
        
            End Class

Any assistance would be greatly appreciated (I can post the *.designer.vb if it will help..)

Streaming ticker data

Hi Telerik team,

We are evaluating your gridview capability to see if you can stream data onto grid without grid hanging or using up lot of memory. We are looking at update rates of around 10,000 quotes per second. Can you let us know your gridview has the capability to do so and if so can you point me to some examples. I would like to evaluate your grid and if it fits our needs we can plan to buy the product.

Thanks

RadHostItem does'nt work in my ribbonBarGroup

I want to add some winform controls in my ribbonbargroup using the RadHostItem. I follow some tips found on this forum but they don't work for me. My ribbonBarGroup is empty

Here is my code :

                    Dim Foo As New TextBox         
            Foo.Text = "Bar"         
            Dim hostItem As New RadHostItem(toto)         
            MyRibbonBarGroup.Items.Add(hostItem)         

So, I though that the proble came from the add method. I tried the same code replacing the hostItem by a RadButtonElement control and it worked fine.

That's why I think the problem comes from the radHostItem.

Horizontal Auto Scrolling Behavior on Cell Click

Hello,

I have several custom width columns in my RadGrid and when I click in a cell that is partially displayed the grid horizontally auto scrolls to bring the entire column into view. This functionality is great in most cases but when the column contains buttons it causes undesired results.

IE: Cell contains several buttons but the entire cell isn’t visible within the grid. When the user clicks the first button the grid auto scrolls, bringing the column into view, but the button click event that fires is for one of the hidden buttons instead of the button clicked. We think this is happening because the auto scrolling fires before the click event and since the mouse cursor in now on a new button after the scrolling it fires that event instead of first clicked button.

One of two solutions will work for me.

1. Either suppress the auto horizontal scrolling so the column doesn’t shift into view.

Or

2. Make sure the proper button click event fires.

How do I make either of these happen?

Regards,
Mike
