CommandBarToggleButton unexpected behavior

Hello Support,

I am using v.2015.2.728.40 and are experiencing some issues with the behavior of the ToggleButton and CommandBarButton. The issue is that when clicking on the toggle button, everything is fine for the first time. The response time for the button progressively degrades as you continue using the button. I was able to reproduce this problem by creating a new Project with an empty form, dropping in a CommandBar, then adding five ToggleButtons. Set the togglebuttons to DrawImage=False and DrawText=True. Run the application and in a circular fashion, click on the each button with a short delay in between. You should notice that after a few iterations, the buttons become unresponsive. This behavior is now hindering the functionality of my application.

Thanks

Francisco

Set the row height to fill all grid space?

I am trying to set the row height of the RadGridView element to fill the whole space of the grid instead of showing blank space when the number of rows is less than the height of the grid, the problem is I couldn't find a simple way to do this without many complications and performance issues using different events to set the RowHeight property when the size is changed for the grid. How to achieve this?

[Solved] Hiding filter menu or list filter items

Hi,

if I put a field with many distinct values (like product name) on columns or rows, and I try to open filter menu - it takes time to load all items in selection tree, user fills like PivotGrid hangs. Is it possible to cancel either filling selection tree or cancel the whole filter menu, so user can only sort using up\down arrow?

Thanks

Alex

ChartView + PivotGrid PieChart

Hi,

I'm using a chart view bound to a pivot grid which works rather nicely. I was wondering if these controls together support the functionality of radial charts.

Eg. Pivot only contains Row or Columns. Then we the analysis would be for distinct combination in Rows or Columns show a pie for each aggregated value.

[Solved] 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.
