Hi,

According to this thread: https://www.telerik.com/forums/how-to-force-series-color

Children collection should be used to set specific color for pie element

radChartView1.Series[0].Children[0].BackColor = Color.Red;

However, I noticed "strange" behavior in data bound mode: As soon as reference to Children is made labels are not shown.

You can see this behavior in sample below:

Uncomment any of 2 lines below and you can see labels are not there

Simple form with load event:

And data object:

Hi,

I am using RadChartView to plot a series of points. For each of these points I have a x and y coordinate as well as a standard deviation of the  measurements (each point is in fact a collection of measurements). How can I plot the error bars?

I saw this post explaining the procedure for wpf but I cant find a parallel way of doing it in winforms

Sorry for not providing a starting point but I really have no clue of where to start from 

Hello, I am trying to get data with raddropdownlist and in case the item value selected equals to "nouveau_scénario" it will open automaticly another form else messagebox will be showen but nothing happen in both cases.

I developed this function to get data from SQLSERVER database (this works correctly ) :

        private void Combobox_scénario1()
        {        
            string constr = @"Data Source=****;Initial Catalog=****;User ID=****;Password=****";
            using (SqlConnection con = new SqlConnection(constr))
            {
                using (SqlDataAdapter sda = new SqlDataAdapter("SELECT [LIBELLE],[OID] FROM [AffecAnalytique].[dbo].[DESCRIPTIF] order by [DATEMODIF] DESC", con))
                {
                   using (SqlConnection con = new SqlConnection(constr))
             {
                 using (SqlDataAdapter sda = new SqlDataAdapter("SELECT [LIBELLE],[OID] FROM [AffecAnalytique].[dbo].[DESCRIPTIF] order by [DATEMODIF] DESC", con))
                 {
                     //Fill the DataTable with records from Table.
                     DataTable dt = new DataTable();
                     sda.Fill(dt);
                     
                     //Insert the Default Item to DataTable.
                     DataRow row = dt.NewRow();
                     radDropDownListElement2.Text = "Choix du Scénario";
                     row[0] = "Nouveau_scénario";
                     dt.Rows.InsertAt(row, 0);

                     //Assign DataTable as DataSource.
                     radDropDownListElement2.DataSource = dt;
                     radDropDownListElement2.DisplayMember = "LIBELLE";
                     radDropDownListElement2.ValueMember = "OID";
                }
            }
        }

here the function of selected index of raddropdownlist :

         private void radDropDownListElement2_Click(object sender, EventArgs e)
         {
             Console.WriteLine("fef :"+radDropDownListElement2.SelectedValue);
             if (string.IsNullOrEmpty(textBox3.Text) || textBox3.Text == "System.Data.DataRowView")
             {
                 MessageBox.Show(" Veuillez sélectionner un scénario ");
             }
             else if (radDropDownListElement2.Text == "Nouveau_scénario")
             {
                 this.IsMdiContainer = true;
                 Nouveau_Scenario = new Form_Nouveau_Scénario();
                 Nouveau_Scenario.MdiParent = this;
                 Nouveau_Scenario.Show();
             }
             else
             {
                 string message1 = radDropDownListElement2.SelectedValue.ToString();
                 string message2 = radDropDownListElement2.Text;
                 textBox3.Text = message2;
                 textBox4.Text = message1;

             }
         }

Hello,

We have a need to create a custom sort order for columns in a pivot grid.  (It's more like creating a Column Order rather than a Sort.)  For example, the columns are Size and the (Header) values are "S", "M", "L", "XL", "XXL" and the columns need to be displayed in this order.  The Row values would be the quantity ​for each size.  And to add a twist, the "Size" values are dependent on the product.  For example, a different product would have Size values of "S/M", "M/L", "L/XL".  So this functionality would need to be dynamic. 

Is this possible?

Thanks,

Mike

Hi,

I'm trying to use the autocompletebox in a way so I can use it to visualize filters in a search. In order to do that, I want to add a tag to the textblock element in order to later on identify the category of the text in the textblock element. I tried to play with the createtextblock event and formatting, but it doesn't quite work out. Can you give me some guideance? 

Thanks in advance!

I use a LineSeries show points in a ChartView with data binding.

I want to change specific point style by specific condition from bound data.

How to do that?

Example: if data value bigger than 10 and change the point size to bigger.

As title.

I need to change specific point style on LineSeries.

How to add placeholder in empty node? So that when added to a node, the placeholder disappears, and if the number of objects becomes zero again, it appears again.
