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.

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.

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
