get raddatePicker on ItemCommand

I was trying to follow the same code here on a telerik web site, becuase I need to do the smae thing, however it keeps telling me that I cannot get ahold of the raddatePicker that I put on the editform template, I am guessing its cause i am binding to a datatable. I need to be able to get a hold of the raddate and time pickers and store them in a session datatable until i insert them into a database.

If Session("Table") IsNot Nothing Then

dt = DirectCast(Session("Table"), DataTable)

End If

myradGrid.DataSource = dt

'populate RadGrid with datatable

Session("Table") = dt

End Sub

Heres my code to try to get at the insert into the datatable but it will not allow me to get at the raddate or time pickers, says cannot be converted from table cell.

Protected Sub myradGrid_ItemCommand(sender As Object, e As GridCommandEventArgs) Handles myradGrid.ItemCommand

If (e.CommandName = RadGrid.PerformInsertCommandName) Then

Dim dt As DataTable

dt = DirectCast(Session("Table"), DataTable)

Dim drValues As DataRow = dt.NewRow()

drValues("Date Begin") = dtbegin.Text

drValues("Time Begin") = timeBegin.Text

drValues("Time End") = timeEnd.Text

dt.Rows.Add(drValues)

'adding new row into datatable

Can you change the shape of the bars in a column chart?

I have a client that wants the bars in a RadHtmlChart column chart to have shaped top rather than the default squared end (see attached).

Is this possible? If so, how would I do it?

making non editable the grid column

Hi Team,

I am using the telerik dll version of 2014.2.724.45

I am facing one issue while editing the grid.

Let me explain the issue.

I have a grid with 5 columns in it and has some data populated. I am implementing batch editing(with batch editing type=cell) for this grid.

When I click on the add new record I am inserting a new row, here I don't have any issue.
While updating the record I want to make one column non editable, other columns are editable.
How can I achieve this.Please see the aspx and .cs files below

At what point in the server's page/controls lifecycle should I re-order columns

Scenario

I am creating a user control that contains a RadGrid. The user control will have properties that specify the order of the columns in the RadGrid. I plan on using code similar to the snippet taken from http://www.telerik.com/help/aspnet-ajax/grid-reordering-columns.html

GridColumnCollection cols = grid.MasterTableView.Columns;

GridColumn c = cols.FindByUniqueName(columnName);

if (c != null){

int start = c.OrderIndex;

for (int i= start; i < cols.Count; i++)

{

c = cols[i];

if (i < cols.Count - 1)

c.OrderIndex = i+1;

else

c.OrderIndex = start;

}

Question
1. At what point in the pages life cycle should the code be executed? (i.e. page_load, page_init etc)
2. If I do not want to execute the code based on the page lifecycle, are there event(s) based on the RadGrid's life cycle that can be used to execute the code? (i.e. RadGrid1_Init, RadGrid1_Load, RadGrid1_PreRender, RadGrid1_ColumnCreated etc)
3. Any gotcha's I should be aware about?
