When the user has added a new row in my grid the column values are written to the database.

In the UserAddingRow event I ask the user "Are you sure you want to add values to database?", and I set e.Cancel=true in case the answer is no.

If the user starts adding values in the grid, and then changes his/her mind and try to close the application, this question from the UserAddingRow event fires, which is not how I want it to be. If the user wants to close the application, the application should close.

I've tried capturing the FormClosing event to set applicationClosing=true and add a check to this in the UserAddingRow event, but the FormClosing event fires after the UserAddingRow, so there is no help there.

Is there another way to prevent the UserAddingRow to be handled when the form is closing?

 Hello, I changed the version of telerik components, had version Q32010 and moved to Q2 2011, and in view of the scheduler in month view, got an opacity. Could answer me how can I resolve this problem?

Hi,

We are developing a new GUI to our system, which is built on top of a legacy code. In details, we write our User Control as a COM (CCW) object that contains the RadGridView and is then placed in the old GUI. The GridView should act mostly in read only mode. Since the communication between the old system and the new system is through the COM interface - it led us to choose the XML populating method to populate our grid. We've sent the XML as a string to the user control. It worked perfectly when we needed only text to be shown in the grid.

Now, we need to be able to show several types of data and several sub-controls in the grid cells (i.e.: GridViewComboBoxColumn, GridViewCheckBoxColumn, GridViewDecimalColumn, GridViewDateTimeColumn, GridViewImageColumn). The way it works now is:
(a) Loading the XML into a source DataTable, using ReadXml
(b) Building a new target DataTable with the needed data types
(c) Adding the right data columns to the Grid
(d) Iterating through the source DataTable and copying each cell to the target DataTable
(e) Assigning the target DataTable to the grid as its Data Source.

As expected - this process led to performance issues...

So, we would like to know if our solution is correct? Is there another way to populate the grid under our limitations?
(Even if we bypass the process of building the XML in the legacy system, and accessing the DB directly, we still need to iterate through all the cells and copying them)

Thanks,

Hi,

I am currently working with the radRichTextBox control to format plain text.

I must replace certain keywords such as <%sender%>, with the text 'You', and then format this in bold font. 

I am able to add additional text to the RTB, however it is added at the end.  

Please help

Hello
I have bought Telerik Full verion with Source code an so on.. I have started to use it and it seems to fit perfectly with my needs.
I have only a problem
There are some examples in RadControls for WinForms Q2 2011 Demos (I have attached a picture) and I cannot use those examples.

I am working in VB.NET. So How could I take the code from examples and create an application? What do I have to do?

Hi,

I seem to be getting a wierd glitch in the display when using a small number of items in the Carousel.

If I have 6 items in the list and I set the number of items to display to 5 it works as expected.

However, there is room to show all 6 items so I want to set the the VisibleItemCount to 6 so all the images are visible.

This causes the Carousel to have a stange effect at the ends of the path. One end often ends up with a blank space (so that only five images are showing, the 6th one has somehow gotten 'stuck behind'. In addition, the other end of the Carousel seems to drop an image with an flicker when changing the selected item.

I have a simple code example for this behaviour:

Demo Code (Zip File)

Is there a fix for this issue - or a known workaround?

This may be related to Bert's issue with small numbers of items not displaying in a sensible manner (I get that too).

Forum Thread

I'd like to be able to use the Carousel to show user entered items - but this breaks down when there are only a few items -it's fine once the user has added enough that the Carousel can't show them all at once - but while there are only a few in the list there seem to be a few odd behaivours going on....

There's another interesting effect that happens when there are only two items in the list. Clicking either of the arrows moves the second item to cover the first. Clicking again moves it back to the other side of the path. I can see how this is behaving consistently with the coverflow style design, but it looks strange with only two items. (Which is bound to happen as soon as you start letting users add their own content - because it'll start empty).

Is there any way to make a simple image list look like a Carousel (i.e. get all the reflections and things). I was thinking that one workaround would be to use a simple image list for the items and then swap out the list control for a Carousel when the number of items gets high enough? (The trouble with this in my initial tests was that it's hard to make the look and feel consistent - it suddenly "jumps" from a simple looking list into being a fancy dynamic control - which is jarring)

Alternativly is there a way to get more direct control of the elements in the Carousel, so you can manually position them when there are only a few?

I'm pretty new with these controls so any hints would be welcome :)

Is there a way of playing with the animation settings on the Carousel? For example, setting the speed at which the items spin when you change the selected item?

It seems that it can rotate very fast; If you click an item at the far end it will shoot across the screen to the selected item location. However, if you select the item that's right next to the selected item location it kind of slowly eases it's way over like there's no hurry...

I'd like to be able to be able to whip round really quickly, even if I'm only moving one item round the Carousel, to get that super-responsive feel that you get from iPhone applications.

When writing a scroller in JavaScript I got the high speed effect by moving the items 50% of the distance to target each frame - so they shot very quickly to almost in place, then smoothly slotted in just as the end. Are such tweaks accessible for the Carousel animations?

Any pointers would be much appreciated :)

 

I use RadListView with property ShowCheckBoxes = true.

1. Business logic requires me to disable CheckBox for certain item. How can i do that?
2. As alternative i would like to disable the whole item, not it's checkbox. I try to do that this way:
...
foreach (var item in lvListView.Items)
    item.Enabled = false;
...

This source does not work - after it all items are still selectable and their checkboxes are selectable too. 

Hi,
I'm trying to build the gridview to be exactly or almost like Microsoft crm 2011 advanced find.
where to start?

• How to make 2 or more Rows Most Left column Span together/Grouped , Group as And and Or
• How to make the Grid as like that Editor, each column has combobox.
• Exactly on which event we can customize the rows or layout and Data?
  I tried the RowFormatting and Cellformating.
• I've got another case, which I use the Grid to display success and Error Record I bind it to A SubObject.

      Because I bind the Grid to many type of object, it just so Many typing to set the autogeneratecolumn to false, and do one by one.
      how do you control the layout of autogeneratecolumns? especially if my Object Property is List.
      that property is the ErrorList and there is another one ValidationError which is also a LIst, when i set Hierarcial to True and      autogenerate to True . It did can expand to bottom , but again the Width is too small because of many properties, and how do you control the Expanded GridView Layout? how do you control the visibility? . What I'm trying to achieve here is AutoGenerateColumns=true and Hierarcial=true but can set What to displayed and the Width.
