With Standard comboboxes, I would set up a Key and Value. When I try the same with the RadDropdownlist, I get an error, when I try to get the value for the SelectedItem.Key.

The following code block is how I populate the RadDropdownlist. This works just fine. Notice line 10 and 11 where I set the members as Key and Value

 

When I enter the following code for the SelectedIndexChanged event, I get the error at line 07. Is there a way I can make this work with the radDropdownlist?

 

I appreciate your input!

 

 

We are opening a usercontrol inside a RadPageView. And in that usercontrol we have a text box with tabindex 5 and we want that when the usercontrol load the focus should be to that control and we have tried  textbox.focus() and textbox.select() method but nothing is working. Please help in this regards

Hi,

I meet a question on BeginEdit() function. When I call "this.gridView.Rows[1].Cells[1].BeginEdit();" , the text in Rows[1].Cells[1] will be selected so user will overwrite the previous text with the new type. I notice  System.Windows.Forms has a function  "BeginEdit(bool)" in GridView so developer can call

"BeginEdit(bool)" to not select any contents. Does Telerik has any similar functions to help me unselect text in a Cell? Or How can I unselect text in a Cell programmaticly if I call BeginEdit()?

 

Thank you,

Chen

Hello,

i have a Gridview which is bind with a table adapter to a database. On this form i have a button for deleting records and it works very well. When i'm deleting a record and i'm refill the table adapter i immediately see the changes.

But here's the problem. When i'm trying to insert a new user from a another form (not that one, where the gridview is), then the changes are not updated.

I've tried to Refresh the MasterTemplate from the other form, but that doenst work. Also i placed a sub on the form with the gridview and tried to call it from the other form, but that doenst works neither.

But when i place a button on the original form where the gridview is and i fire the sub with the button, the changes are working well!

Can anybody help me with this issue?

I need to perform data retrieval and analysis on recurring appointment instances that exist in the future.

Here is the business logic:

1.  User selects a date & resource combination.

2.  Application pulls instances from scheduler tables.

3.  Instances are loaded into var or datatable for application retrieval and analysis

Problem:

Instances of future recurring appointments do not exist in scheduler appointment table so I cannot perform a filtered retrieval.

Question:

How can I perform this action?

Hello,

Hello,

 

So I am new to Telerik Winform. I had amazing experience using Telerik. But what I still don't get it is how to use the RadLayoutControl.

As far as my understanding, RadLayoutControl provide a customize layout template design method completed by user drag and drop controls on the LayoutControl object (what I called layer 1).

My questions is when I wanted to place a control on top of a control that already top of a Layout control(which I called layer 2), system treat my intention as I want to place another Layer 2 control which I wanted that control to be placed on layer (e.g. place a control on collapsible panel).

Do I misunderstand the purpose of layoutcontrol?

 

Sorry for my bad english.

Hi,

I have a radgridview that is populated with data via a LINQ query.

LINQ returns an async list and if it is not a null list the datasource of the grid is set.

After the grid is populated I want to be able to grab multiple rows in it (perhaps by holding CTL) and then drag these rows into another grid / control.

I have got this to work on a grid populated with simple data via a loop. I can't get it to drag when it has a datasource set.

Can anyone help?

Thanks,
Martin.
