Let's say I was had a radgridview that was grouped by foodtype, whose sections included fruit.
Currently, when I try to add a type of fruit from the top, I cannot add specifically to the fruit section because the foodtype section is not there, and a new section entitled "foodtype:" is created.
How would I be able to add to the fruit section from the grouped interface?

I have RadChartView that receive real time data and i want to add the option after the mouse is over specific point to see it's value so i added this property:


And now i can see an empty rectangle with no text (see my attach file).
Another thing that i have notice is now after right click on my chart i have an new option called Palette that change my series color and in this case i can see the point value inside the rectangle.

Now i have 3 questions:

1. What is this new option ?
2. how can i see my point value without change this color ?
3. is it possible to add some text inside this rectangle ?

Thanks !

Hi:

We are working with some existing code.  The RadDropDownList controls throughout the application allows any data entry in the control (for example: a list of USA states, I could enter Fred and tab out of the field).  Currently, all RadDropDownList controls DropDownStyle are set to DropDown.  What are the best practices constraining the users data entry to the supplied list.

I have a whole bunch of timepcikers on a form. I need to have a button on the form to set all times to 12:00 AM. It is a rest for the user. I wanted to do something like this:


foreach(Control c in this.Controls)
{
if(c is radTimePicker)
{
// set time here ;]
}
}

I'm not sure what I should use for "Control" and "this.Controls" I'm guessing radTimePicker is correct.

I am applying filter to a radgridview as
 ((DataTable)Grid.DataSource).DefaultView.RowFilter = TxtBxExpression.Text;
                ((DataTable)Grid.DataSource).DefaultView.AllowNew = true;
                Grid.MasterTemplate.Refresh();
                Grid.MasterView.Refresh();  

After that when I am trying to insert a row as 
Grid.Rows.Add();

It is inserting a row at the end but it is without any columns and not even dropdowns of the rows are selectable so that I can change the row values and the update the data.So I want a row that has columns and its dropdowns are editable.So how can I do that?

We have a data grid view which we would like to apply a few conditional rules programmatically. We would still like the end user to be able to add their own conditional formatting rules, however; we would like to block them from deleting the rules that we added via code. Please see the attached screenshot for an example. How would I go about doing this?

For my first attempt I subscribed to the the ConditionalFormattingObjectList.CollectionChanging event. The problem is that the Action received in this event is all of type Reset first, Add second. Basically the ConditionalFormattingForm is first clearing the collection and then re-adding the all the conditions. Additionally, when you cancel the collection changing the UI still reflects the changes even though you have canceled the event in the underlying collection. Should I be using a different event. Perhaps one on the ConditionalFormattingForm itself?

Thank you,

Hi,

i will attach 2 screen shots to this post. in the first you can see how the first column is almost collapsed and the second pretty wide.
I would like to set the ValueColumn width in code. Here is my current code which is not changing the ColumnWidth no matter which value i put there.

 this._gridError.PropertyGridElement.PropertyTableElement.AutoSizeItems = false;
this._gridError.PropertyGridElement.PropertyTableElement.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
this._gridError.PropertyGridElement.PropertyTableElement.ValueColumnWidth = 300;

The second thing I would like to do i to display ScrollBars in the PropertyGridElement.SplitElement.HelpElement.ContentText box.

Thx and best regards,
Darko

Hi

( First of all I need to clarify that I could manage both C# or VB solution to solve this issue )

I have a RadListControl where I would like to use it to list the runing processes in the system (with a condition that no more than 1 process with the same name),
that thing is done and I'm trying to update the list each 2 seconds (firstly determining If exists changes to update the current list),
I'm saving the SelectedItems property of the control to restore the selected items in the RadListControl after updating the list and here is the problem, after clearing the items of the control using the Items.Clear method the Scrollbar moves up to the top of the control and I need to scrolldown to the desired position again and again.

I would like to keep the current position after updating the items in the control, just like Windows TaskManager does for example.

I also tried to set a collection of RadDataItem as the control DataSource, but then the Image property for each item is empty (I don't know why).

I attached a gif in this post that demonstrates the problem,
As you can see in the Gif, when I run a new process (the window which is at the left border of the gif) the process list is moved to top, and the same thing happens when I close that process.

I don't know what more to try, here is the relevant part of the code:


Thanks in advance.

PS:

What I did time ago to solve this issue with a normal ListBox control is this (I can't reproduce it in a RadListControl):

I have Winforms application with ChartView that received real time data and i have label the show the data value. After each point received inside my Timer tick all the points remove in order to show my label only once:private AreaSeries series;

private void timerStatistics_Tick(object sender, EventArgs e)
{
       try
     {
        chartPoints.Add(AdapterStatistics.BitsPerSecond * 0.000001);
        series.DataPoints.Add(new Telerik.Charting.CategoricalDataPoint(AdapterStatistics.BitsPerSecond * 0.000001));

       RemoveLabels();
       series.DataPoints[series.DataPoints.Count - 1].Label = AdapterStatistics.TrafficStatistics;
     }
       catch (Exception)
       { }
}

private void RemoveLabels()
{
     for (int i = 0; i < series.DataPoints.Count - 1; i++)
     series.DataPoints[i].Label = "";
}

my problem is that me label i in the right side of the lase point so almost all the label is hide (see attach file)
Any idea if it possible to remove the label to the left of the last point inside my chart ?

For data binding in winform scheduler, i want to update database when the appointment is added, updated rather than when some update button is clicked.

Currently, the documentations provided is perfectly describing how it work with button, and i love it. Nonetheless, i want to find better, and easy way to update appointment, so we can get rid of using update button.

Is there any event property for radscheduelr that i can use in this condition? or Any other way to do this?
