I have several panels on a form.  I need to dynamically create a CommandBar (vertical in this case) and place it on a panel.  I then need to reposition this panel and resize the one above so that the entire CommandBar is visible.  I would like to set the size and location of these panels based on the size of the CommandBar, but the Size property does not reflect the size required to display all the added buttons.

The CommandBar in the attached image has 5 button, but only three are visible.  If I knew the size of the CommandBar, I could set the Location of the panel containing the CommandBar and the Height of the panel above it, so that all 5 buttons would be visible.

How can I get the information needed to set the Size and Locations of the two panels as needed to make the dynamically created CommandBar visible.

Only users that have Telerik installation version 2021.1.122 are affected.

Symptoms:

Clients that have Telerik installation version 2021.1.122 can not build successfully .NET Core/.NET 5.0 projects. The following error occurs while compiling the project:

The problem is a missing NuGet fallback folder.

Solution:

You should create the missing ToolboxNuGetPackages folder in the installation folder of the controls, usually at C:\Program Files (x86)\Progress\ToolboxNuGetPackages.

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;

             }
         }

Hi,

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
