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.

I have a grid with a custom filter, like the sample in Gridview Custom filtering. How can I select the first row in the grid after the custom filter is applied?

I've tried this code, but didn't work:


Thanks in advance

Hello,

I was hoping someone could shed some light on this situation.

I have a RadPageView with a RadListControl inside.  The list control is populated from a sql table that contains potential 'status' setting for a recordset that is filling a RadGridView also on the same page.  I have the list control MultiSelect set to 'Simple'. The idea is a fast, multi-select filter for the radgrid.

So as with most issues, 90% works great.  Using RadListControl1.SelectedIndexChanged as my event handler I am able to create a filter for the radgrid using OR to allow filtering for multiple status at one time.   If the user clicks status 'a' then status 'b' then status 'c' the Radgrid filters and only shows 'A',then adds 'B',then 'C'.  Perfect! (status LIKE 'A' or status LIKE 'B' or status LIKE 'C' is  the expression I end up with, again perfect)

Here is where is problem lies.  When a user un-selects items in the RadListControl in reverse order (Add, A,B,C then Remove C,B,A) things seem to work, the event handler fires properly.  However, if the user un-selects items in any other order the event wont fire (Add A,B,C  then unselect A,B,C).  I'm guessing this is by design.  Although I have a loop with a message box showing the RadLIstControl items each time the event fires (for debugging).  I don't know if this might have some unseen effect on the control.

So I am wondering, is there a solution for this situation, either using the RadListControl (it's fast) or would there be a better method, I just can't seem to get my head around this one.  My code is in VB if that matters.

Thanks in advance!

Dean.

I'm trying to reload all the items in a RadDropDown box after something new gets added to the database. I have it set up right now that an event gets triggered when an item is added into the database, it calls the Rebind() method on the RadDropDownList, but nothing seems to happening. What should I do to get the RadDropDownList to reload?

Hello
    I have  a  question about  focus on control  TextBox, DropDownList etc.
How is the best solution for highlight control when got focus? Focus primitive, maybe some themes support this functionallity?

Please some example for solution. 

Thanks so much.

Hi There,

Hello,

I use:

• Q3 2010 version 2010.3.10.1215
• Windows 7, Visual Studio 2010, .net framework 4

I try to evaluate RadGridView but with simple file explorer (hierarchy, self reference, unbound mode, load on demand/expansion) and I get exceptions.

 

I isolate problems to simple file explorer. Cound You help me to solve these problems ?

1. Add rows in begin/end section after  expanded event.

Is it necessary to add rows in statements begin/end ?

If I do it, I get exception

2. During keyboard manipulate:

1. enter - expand
2. selected cell chage with arrow keys

 i get exception. It takes some time, but after minutes I always get this exception:

 

3. After column order change I get strange look  columnorderchange.png

My file explorer code:

Cound You help me to solve these problems ?
