Hi,

The current display format for an appointment on scheduler is  appointment time and appointment subject,
eg:  10:00 am - 10:30 am  test

How can we make it display what we want to display for a custom appointment? 
eg: patientName

Thanks,

Hello

I have three tables(Person, Phones, Type). I attached a picture for these tables and relationships.

I want to show the Person table as Parent grid and the Phones table as a Child grid in radGridView and I want to show the Phone Types in a combobox column in child grid too. So I Binded the child grid to the Phones table and added a ComboboxColumn to the child grid then binding it (Combobox Column) to the Type  table.

There is no trouble with it while Inserting a new row but When it loads the data form database it does not show the Phone Type I Selected before.

How can I load data and show the PhoneType Selected (and saved in database)?

I hope you can get me

Regards

Hi

This is a piece of code we have:

private

 

void radGridView1_GroupByChanged(object sender, GridViewCollectionChangedEventArgs e)

 

 

{

 

radGridView1.ShowGroupPanel = radGridView1.Groups.Count > 0;

 

}

 

 

this

 

 

.radGridView1.GroupByChanged += new Telerik.WinControls.UI.GridViewCollectionChangedEventHandler(this.radGridView1_GroupByChanged);

 

It works propely if gris something in it, but does not on empty grid.

Thank you
Lily

I'm getting an error when I try to access a grid cell value, which has no value. I tried using the trycast function, but that didn't work.  Here is my code below.   When the code runs and there's a value the message box show without problem, but if there's no value in the cell I get an error (see attached file).   The grid is loaded from the a sub call (see below)  Need to know how to handle this situation.

Thanks,
Tom

Hello,

Recently I needed to hide the column that represents the slider's records RadGridView (leftmost column of the GridView) to all appearances, it was enough to indicate "AllowColumnChooser" as "false ".

But even setting the value of "AllowColumnChooser" as "false", the selector of records continued to appear.

I also realized through the method attempts ".HideColumnChooser()" and neither worked.

Finally I found it was necessary to set the property value "ShowRowHeaderColumn" to "false" to get the picker does not display records.

Questions:
1. What is the purpose of property "AllowColumnChooser" and method ".HideColumnChooser()"?
2. What is the explanation for me to use the property "ShowRowHeaderColumn" and the result is to hide the column chooser?

Control and Package Version:
* RadGridView

Hi, I was wondering if I could add a new button to the footer of a RadCalendar?

Hi,

I want to use RadListControl to display the logs of the ongoing large process in background thread. I will be adding hundred thousands of items into the control in main thread.

But to make everything simple, before adding item to the control, I am checking if the item count is more than 100, if it is more than 100 I am removing the top most Item, then only I am adding the new item. After adding I am scrolling the listbox control down to the last item.

This process may run for more than 10 hrs and my application may not respond as it is dealing with too much of items every seconds.

I am looking for most efficeint way to do this as with listboxcontrol after running for about 1 hr application is not able to handle the number of items and not responding.

I am using following code: 

            RadListDataItem newItem = new RadListDataItem(message);
            radListControl1.Items.Add(newItem);
            if (radListControl1.Items.Count > 100)
            {
                radListControl1.Items.RemoveAt(0);              
            }           
            radListControl1.ScrollToItem(newItem);

But if I am using windows listboxcontrol I am able to do without any problem.

            listBox1.Items.Add(message);

            if (listBox1.Items.Count > 100)
            {
                listBox1.Items.RemoveAt(0);               
            }
            listBox1.SelectedIndex = listBox1.Items.Count - 1;
            listBox1.ClearSelected();   

I want to use RadListControl because it can handle html syntax.

Please suggest something on this. I can even switch to another control which supports html code.

Bibek Dawadi
