Hello,
I want to select record in grid using my object ID.
Eg. I have collection of Customers. Each customer has ID, and I have one Customer with I want to select in gird. The problem is that my customer has different reference than customer in RadGrid but the same ID (so SelectedItem  doesn't work).
I know that I can first get the customer reference searching my collection (eg. using linq), but there isn't any comparer mechanism to set in RadGridView?
In most cases we override Equals() method on our objects, but sometims data comes from Web Service and we use Add Service Reference option, so we can't have influence on class definition.

Hi,

the mask modifier does not seem to work for me. I use the following mask (for ICD codes) in a RadMaskedTextInput: ">Lnn.nn". But the '>' character is shown instead of forcing upper case style.

Hi,

the masked text input control has some nice features I would like to use for "normal" text boxes, too. Is there a way to use no mask?

Or to have a mask to allow a variable lengh of text, sth. like "a*" ?

Regards, Felix

hi 
I need work with Alert content in right to left mode ?

Hi,

I'd like to clarify whether this is an expected behavior.

I'm creating a windows explorer-like control where the RadTreeView is used on the left side pane (l-pane) for navigation and a RadGridView is used for right side detail pane (r-pane).

When the node in the tree is selected, its children are displayed in the r-pane. When a row in r-pane is double-clicked, l-pane will navigate to the node corresponding to that row (if there's any child under it, otherwise there will be other behaviors), and the children of that node populate the r-pane.

I'm using MVVM. Each node in the tree and row in the grid view is bound to a view model. The same view model is used for both the node (if it appears in the tree) and the row element (if it appears in the grid view). And I'm controlling the IsExpand and IsSelected status of the tree node through the view model's corresponding properties with the same name (two way binding). All very standard.

I also have a view model for the whole explorer. In here I hooked a few ICommand's to the various events of both the tree view and the grid view. For example, I created an ICommand for the Selected event of the tree, so that when the user select a certain node, I'll update the r-pane's bound collection. Another ICommand responses to the grid view's MouseDoubleClick event so when the user double click the row in grid view, the entry view model's IsSelected and it's parent's IsExpanded are set to true. And here's where the problem occurs.

Let's look at those nodes previously not shown in the tree yet (i.e. their parents are not expanded yet).

After the above step the tree successfully expands and shows the node in question as selected. After that what I expected is that the 'Selected' event of the tree view is fired, my ICommand for 'Selected' is executed, and my r-pane is populated with the node's children. But the 'Selected' event is never fired!

The reason i guess is that, since the node's parent was not expanded yet, the node was not visible/loaded in the tree when my ICommand for r-pane's MouseDoubleClick was executed. And what's more, even after I set its IsSelected property to true programmatically, somehow the event routing just stopped there.

One interesting thing I found is that, if I manually expand the parent in the tree, and make the node visible, then go back to r-pane and double click on the row, the 'Selected' event is fired now! I can see the r-pane is repopulated with the node's children.

 It seems that after I expand the parent once, even if I immediately un-expand it afterwords, I somehow trigger the node to be loaded in the tree. And now it's legitimate to wake up the 'Selected' event of the tree view control!

Here's the Link to the demo project on skydrive. (RadTreeViewProblem.rar)

My question here: is this expected? Of course I can set all the nodes in the tree to be Expanded when it is loaded to make this work. But that's certainly not what I want.

Any input on this is appreciated!

Hi Telerik Team,

Great work with your controls, they really are a pleasure to work with!

Currently I'm using the ScheduleView and looking for a way to customize the MonthView to display next to the number of each day an indication of the number of items in the system.  E.g. "12  (2 entries)" meaning there are already 2 entries scheduled for the 12th of the month (and those 2 are not necessarily contained in the bound AppointmentSource).

What would be the best approach to accomplish this?

Thanks in advance.
Etienne.

I have 10+ columns in my radtreelistview control

when i scroll or expand, the responding time of the control is quite slow

for example, while expanding a node, even it only has like 1 or 2 child rows, it still take a long time to load

i have tried to 'hide' most of the columns, then the responding time becomes instant

is treelistview not designed for such purpose

or is there anyway to work around this???

Hello

I have Combo Box column in grid with data member binding for id.

The problem that the Filter shows the Ids instead of the names

How can I show the name without change the data member binding or the filter?

See picture attached.

Best regards

Ehud.

Hi,

I need to have the ability to move the rows of a radgridview up/down without rebinding the grid. The gridview is grouped on two groups.

Is there a quick and simple way to do that?

Thanks,
Arpit

Hello, we just updated our DLL's to Q2 2011 (CLR 4.0), and we noticed that the field filter drop lists are not allowing independent values.  For example, if you select "Contains" for Filter1, then Filter2 also becomes "Contains".  Likewise, if you select "Starts With" for Filter2, and Filter1 already is set to "Contains", Filter1 changes to "Starts With".

We are not overriding any functionality with Prepare, etc.

Thanks for any info.
