Span multiple columns with gridview header

Is is possible to span multiple colums with the gridview header text? Or to turn off the header text on a particular column in a gridview while still showing the column? In other words I have two columns 'origin city' and 'origin state' and I would like one header across both columns that says 'Origin'

How to enhance limited iCalendar support

Hello,

in my app I have to import and export iCalendar data. I do not use data binding. iCalendar format is used to persist data.

Unfortunately the existing implementation is limited.Only a subset of the appointment properties are exported. For example resources are completely missing. Is there an "easy" way to add resources for import/export?

A second problem is double import creating double entries instead of overwriting. Every VEVENT has a uid property which uniquely identifies the event. This should not create duplicates on import.

Regards
Martin

Please help me.

Hello,
I have a Main Form which is a MDI Container. When a child form which is maximizable, is maximized by the user and the user tries to show another child form which its MaximizeBox property is False, the latter form also maximizes(because the former one is Maximized). How do I must prevent such an action to occur.
please help me,
Thank you, Tooraj Azizi.

Getting .text from dynamically coded menu

I am trying to get the .text property from the programatically added menu items in my click event. I need the .text of the menu item to determine the ID I am putting in to the database table for my report.

These menu items are generated based on what models we are currently producing. These models are housed in a .txt file in my project. I have it set up this way, because in the future we need to allow easy adding and removing of model numbers and I did not want to set up a database table for 2 - 5 model numbers.

The first snippet is the code in my click event for the menu item.
The second snippet is the code I am using to generate my menu items at runtime.

Private Sub mnuItemModel_click(ByVal sender As System.Object, ByVal e As System.EventArgs)

Dim connStr As String

connStr = "*****"

Dim insertString = "INSERT INTO REJECT_REPORT (REJECT_ID) SELECT dbo.fnRejectRpt_Next_ID('" + modelNumber + "')"

Dim conn = New SqlConnection(connStr)

conn.Open()

Dim comm = New SqlCommand(insertString, conn)

comm.ExecuteNonQuery()

conn.Close()

loadGrid()

End Sub

Dim mnuItemAdd As New RadMenuItem("&Add")

Dim mnuItemAddModel As New RadMenuItem("Model")

mnuItemsTools.Items.Add(mnuItemAdd)

mnuItemAdd.Items.Add(mnuItemAddModel)

AddHandler mnuItemAddModel.Click, AddressOf mnuItemAddModel_click

Dim reader As New System.IO.StreamReader(filePath)

While Not reader.EndOfStream

Dim currentLine As String = reader.ReadLine

Dim mnuItemModel As New RadMenuItem(currentLine)

mnuItemAdd.Items.Add(mnuItemModel)

AddHandler mnuItemModel.Click, AddressOf mnuItemModel_click

End While

Grouped Column Header Text

Hi

I'm using version 2010.2.10.713 radgridview with persian localization & RTL layout. Everything is fine except for when a column is grouped. Although my column names are in persian, the headertext of the grouped column is not the column original HeaderText, but it seems that it is the unique name of that column. How can I fix it to show the Persian HeaderText instead of column unique name when a column is grouped?

Thanks

GetCellElement / GetRowElement always returning nothing

Hi,

I have a RadGridView control, which has 9 columns, created at design time. The control is being populated with data at run-time.

I am populating the RadGridView by using the Add method:

RadGridView1.MasterTemplate.Rows.Add(... some values...)

After populating I am iterating each row in the control as follows:

For Each row As GridViewRowInfo In RadGridView1.MasterTemplate.Rows

I want to get the cell element for the second cell, which I believe I have do do with the GetCellElement method:

RadGridView1.TableElement.GetCellElement(row, RadGridView1.MasterTemplate.Columns(1))

However, GetCellElement is always returning Nothing. I can step through the code using the debugger, and both the column and row exist. I have tested GetRowElement, and this also returns nothing.

I need the CellElement as I want to enable and disable the cell based on some criteria. Each row potentially contains child rows.

Why do I always get nothing? Is there a problem with the way I am using GetCellElement, or do I need to iterate the rows differently?

*EDIT* Forgot to say, I am using the latest version of the Telerik controls (Q2 2010 SP2).

Thanks in advance,
Matt.

DropDownHeight

Okay, so I have tried setting every property I can find with the word "Height" in it but am still unable to simply specify how tall the drop-down is. Currently I have three items in it, each with an image. When dropped down only 1 item shows and I want all three to be visible. Seems like this should be way more intuitive, like with a property called "DropDownHeight", but it does not exist anymore.

Any help is appreciated.

Thanks!
