Autocompletebox Bug after reopen the form?

Hi,

I've developed a windowsform application where the user build a filter using autocompletebox components.
This webform is called by the showdialog function. It works fine, but, when I reopen the form, the autocompletebox brings 2 values when I've set just one. It duplicates the value, and then I have 1 TokenizedTextItem and 1 text, as you can see on the prinscreens.

The first print is my selection on first time, and the second print, is when I reopen the form.

Activate calendar using keyboard

Hi,

I'm trying to find a way to activate the calendar of a RadDateTimePicker control and show the popup using the keyboard instead of using the mouse. What I would like is to activate the popup when the user performs a key combination of ctrl+L or ctrl+?. How would I go about doing this?

GridView doesn't display data when its cell has combo box

Hi,

I try to follow the following link to insert a combo box into my gridview.
http://www.telerik.com/help/winforms/gridview-columns-gridviewcomboboxcolumn.html

However, When I copy and paste code of "Binding to collection of custom object", my gridview doesn't display it data (see my attachment). when I click on second cell, it can display its combo box. When I select a value in combo box, it seems the grid doesn't update value.

I want the following requirement.

I have a class. for example:
class A {
Id,
Field1,
Field2
}

I want to display list of A into my grid.
Column 1 is Id of a A
Column 2 is a Combo box, it gets data from BB. when user selects a value of its combo box, the value will be set to Field2
Column 3 is a Combo box, it gets data from CC. when user selects a value of its combo box. the value will be set to Field3
Column 4 is a button. The button is displayed as an image. When user clicks on it, the current row will be deleted.

Can you instruct me ? I'm quite new with telerik control. Nice day.

RadForm Drag Once DataBinding

I am evaluating Telerik Winforms tools and am pretty impressed so far. I am experimenting whether or not to go "all in" with using the Telerik controls in order to take advantage of automatic theming and such. One of the features of using stock MS controls and Windows is to be able to utilize Drag Once Databinding to auto generate a screen which then allows me to modify the screen in design mode without needing to add each element one by one and then connecting it to the datasource. I found that I could easily change the default datatypes to use Telerik controls and it works well when using a standard Windows form. However, when I try to generate the screen elements using RadForm the Data Source window does not give me the option to select either Details or DataGridView in order to drag the datasource onto the form and autogenerate the screen elements. Any thoughts on what I've done wrong or any work around solutions? Many thanks....

TextBox scaling with Microsoft Sans Serif font

Hi,

When I use a telerik textbox, and set the font to Microsoft Sans Serif (size 11,25 pt) (see A in the attachment), some characters are not displayed fully. When I use Segoe UI it is rendered correctly (B in the attachment). Looks like the scaling of the component does not work 100%. Setting autosize to false does not work either: I am able to scale the control, but the 'inner textbox' stays too small.

Best Regards

Edit GridView bound to MS SQL Server Dataset Error

I am having some issues trying to edit rows in a GridView that is bound to a MS SQL Server dataset. I created a new test project to make sure it wasn't something else in my code somewhere that is causing the issue. The test project only has a form with 1 control on it (rad gridview) I created a dataset in VS Studio 2012 and bound the gridview to it. Whenever I attempt to update a field in the gridview I am getting the error message: DataTable internal index is corrupted: '5'. I did some research and this error can happen when you are accessing a datatable from multiple threads - which I am not. I have another application where I use the same code with a local MS Access database and the code works perfectly. Here is the code in my test application:

Public Class Form1

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

'TODO: This line of code loads data into the 'IT_InventoryDataSet.InventoryRun' table. You can move, or remove it, as needed.

Me.InventoryRunTableAdapter.Fill(Me.IT_InventoryDataSet.InventoryRun)

End Sub

Private Sub InventoryRunBindingSource_CurrentChanged(sender As Object, e As EventArgs) Handles InventoryRunBindingSource.CurrentChanged

End Sub

Private Sub InventoryRunBindingSource_ListChanged(sender As Object, e As System.ComponentModel.ListChangedEventArgs) Handles InventoryRunBindingSource.ListChanged

If e.ListChangedType = System.ComponentModel.ListChangedType.ItemChanged Then

Me.InventoryRunTableAdapter.Update(Me.IT_InventoryDataSet.InventoryRun)

End If

End Sub

End Class
