Hi Team,
I am new to winform development.
I have bound the RadDropdownList with values from database with DisplayMember and ValueMember properties set properly.
I can see the items in dropdown with no problem.
But when I want to assign the value to RadDropdownList, it sets always to 0 (zero).
Please take a look at my code to bind dropdown :
And in another method, I am setting the value of dropdown :
But every time I get SelectedValue as 0 (zero).
Can you please tell me how can I set the value of the RadDropdownList?

pub void SetControls(){ // Fill DataSet ds with values from dbFillInvoiceTypeCombo(int.Parse(ds.Tables[0].Rows[0]["AccountJournalEventTypeID"].ToString()));cmbInvoiceType.SelectedValue = int.Parse(ds.Tables[0].Rows[0]["InvoiceTypeID"].ToString());}But every time I get SelectedValue as 0 (zero).

Hi Telerik,
I got 2 forms...I got some datagridview in the form2. I want to change the column header names into French when the user clicks on the french button.
I have created a method in Form2 and called from Form 1:
I made the radgrid modifiers to public and the radpageview changed to public. When i excute it nothing is changing. When i test with RadMessagebox, it works.
Please assist me. Thannk you.

//Form 2 where I want to change the col name of the radgrid
internal void changeRadGridview()
{
radGridView1.Columns[2].HeaderText = "First Name";
radLabel5.Text = "hi";

I was wondering how exactly exceptions are stored. In the master event's recurrence rule?
For example, if I had deleted an occurrence of a recurring appointment, how would that be stored in a database? Maybe something like DELETEDDATES=ddMMyyyy in the recurrence rule?
Thanks!

Hi everybody.
I have a problem with CurrentRowChanged event of GridView. My problem is next.
At form's load event I do this: (rgvClientes is the GridView)
this.rgvClientes.CurrentRow = null;
this.rgvClientes.CurrentRowChanged += new CurrentRowChangedEventHandler(this.rgvClientes_CurrentRowChanged);
And when I click on a Row from the GridView the event CurrentRowChanged fires twice but only the first time, after that it fires only ojne time when a click on a different row.
Someone can explaine me this issue?
Thanks an sorry about my English.

Hello,
I use RadScheduler in my project and my appointments have custom colors, icons etc.
I add appointments to RadScheduler manually in the following way:
foreach (var app in appointments)
radScheduler1.Appointments.Add(app);
I have a problem with RadScheduler MonthView. I want to add appointments to MonthView and I want them to be shown sorted by time (IEvent.Start.TimeOfDay), so if app1.Start.TimeOfDay > app2.Start.TimeOfDay and app1.Start.Date == app2.Start.Date then app1 should appear under app2.
I tried to solve this problem by ordering my appointments collection:
var appointments = src.OrderBy(a => a.Start.TimeOfDay);
foreach (var app in appointments)
radScheduler1.Appointments.Add(app);
But this did not help, so is there a way to solve this problem? Actually I need a way for sorting appointments by time in MonthView.
I am sending you an image of the MonthView, where you can see that appointments are ordered in an inccorrect way. Take a look at Dec 20 and you will see the appointment, that appears at the bottom has its Start.TimeOfDay 09:15, so it should appear as the second starting from the top. Why does it behave in such a strange way?
Thank you for your support.

Hi,
I have conditional formatting rules on a parent grid that are defined as expression types
New ExpressionFormattingObject ("COL1",Expression:="COL2 = 1", etc.)
The compare data is in a different column than the formatting. This works OK for the Grid.MasterTemplate.Columns.
I also have identical rules defined for Grid.MasterTemplate.Templates(0).Columns, however the styling does not get applied for these rows on the child grid. If I change the child rules to be ConditionalFormattingObject type as:
New ConditionalFormattingObject ("COL1", Equals, Value:="1", etc.)
the styles are applied correctly. I can't do this though as the data item is in a different column than the formatting. (test against COL1, style COL2)
Is there something I need to do to get the expression rules to format correctly?
Many thanks,
Mark.
