GridViewDecimalColumn and percent format in edit mode

Hi to all,

I would use same format to edit column and visual column for percent value

I'm using formatstring "{0:P2}" to show percent value correctly (value passed by object is for example 0.06), this formatstring show me 6%, OK!

But when I edit cell it shows me 0.06, are ther a way to edit value "6%", keeping 0.06 into my object?

Then my data is 0.06, it shows 6 %, I enter in edit mode and It should show me "6" or "6 %" (masked? I don't know),

I enter 6.5 %, and it store in my data 0.065

Is it possible?

01.Dim _Column As New GridViewDecimalColumn()

02.

03._Column.AutoSizeMode = BestFitColumnMode.AllCells

04._Column.HeaderText = "Percentage"

05._Column.FieldName = "Discount"

06._Column.Name = "Perc01"

07._Column.Width = 100

08._Column.FormatString = "{0:P2}"

09._Column.DecimalPlaces = 2

10._Column.ThousandsSeparator = False

11.

12.Columns.Add(_Column)

Formatstring on dynamic datasource not working

I'm trying to change the datasource for a template as follows

Dim ContactPhonesDS As ContactsDataset.PhoneRow() = ContactsDataset.Phone.Select("ContactKey = '" & ContactKey & "'")

Dim ContactDt As DataTable = New DataTable("Phone")

ContactDt.Columns.Add("TableKey")

ContactDt.Columns.Add("ContactKey")

ContactDt.Columns.Add("Client_ID")

ContactDt.Columns.Add("Office_ID")

ContactDt.Columns.Add("PRNumber")

ContactDt.Columns.Add("Line_Type")

ContactDt.Columns.Add("comboLine_Type")

ContactDt.Columns.Add("Phone_Number")

ContactDt.Columns.Add("Extension")

ContactDt.Columns.Add("Discription")

ContactDt.Columns.Add("Delete_Flag")

For Each row In ContactPhonesDS

ContactDt.ImportRow(row)

Next

PHNumbers.MasterTemplate.DataSource = ContactDt

PHNumbers.MasterTemplate.Columns("Phone_Number").FormatString = "{0:(000)000-0000}"

But the formatstring is not applied. I'm Guessing it's because the column is not of the correct data type, but I can't figure out how to set it to decimal.

GridLayoutRow ignoring sizing

Hi

My layoutgrid is 2 columns, 4 rows and Im seeing the control ignoring both width and ProportionalHeightWeight settings I set.

Rather than 20:80 I'm seeing 50:50 for columns, rather than 10:10:70:10 for rows I'm seeing 25:25:25:25.

Extend MultiColumn ComboBox (new section with buttons)

Hi,

Can I create or extend radMultiColumnComboBox to add a new section below the bottom of the grid, which includes one or more buttons (e.g. New)? After clicking the button(s), a new modal dialog/window will popup, while the MultiColumn Combobox will be kept open (dropped-down list).

Any suggestions or instructions will be very helpful. Thanks!

Regards,
James

How do I set the spacing around tiles?

The attached pic is (touched up) what my designer has asked me to produce for our first rewrite of our product. We've moved to telerik control set from an in house one which is looking dated. The 2nd one is my first attempt.
I've googled for an answer and seen several responses to people wanting to drop the space between tiles, or for ASP css, but in my case where the tiles are created and added to the panorama dynamically, they're all joined together and however much I've played with margins and padding I don't seem to be able to get a space around them.
Can anybody tell me how to do this very simple thing please?

ContextMenuStrip - Is this no longer supported?

Good Afternoon,

I've recently downloaded the latest trial release of WinForms UI controls and our code to set a custom contextmenustrip on a Grid view no longer works.

We need to do this programatically, based on the row being clicked as below:

Private Sub radGrdHistory_ContextMenuOpening(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.ContextMenuOpeningEventArgs) Handles radGrdHistory.ContextMenuOpening

If TypeOf e.ContextMenuProvider Is Telerik.WinControls.UI.GridHeaderCellElement Or TypeOf e.ContextMenuProvider Is Telerik.WinControls.UI.GridFilterCellElement Then

radGrdHistory.ContextMenuStrip = Nothing

Else

BuildAppointmentTypeRightClickMenu()

radGrdHistory.ContextMenuStrip = cmsAppointment

End If

End Sub

Using the Q1 2014 version this correctly showed our cmsAppointment contextmenustrip when rightclicking a grid element but this no longer occurs. I just see a context menu with 'Copy' and nothing else.

All the reading on the docs just says to use the ContextMenu properly and doesn't say anything about ContextMenuStrip. Has support been discontinued for this? Do I need to change all my contextmenustrips to contextmenus? Or do I need to write the code to show the CMS manually (say, off a right click event?).

Base constructor calling CreateChildElements method

Hi. This is my first encounter with the Telerik control set.

As I don't have a clue yet, I'm amending a code fragment I found online to create a custom RadTileElement for my needs.

I'm passing in a database record to a constructor. I've then overridden the CreateChildElements method to map out the grid and set the strings etc according to whatever's passed in. But I noticed, when stepping through the code, that CreateChildElements was being called before my parameterized constructor.

Am I correct in assuming that the base constructor is calling a virtual method?

If the child elements are created before my constructor gets it's turn to set up the control then is there a better way to handle this?

ty in advance
