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,

 

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.
