i have a chart with dates on X-axis , Chart is bound to a dataSource and there are 700 items .
with the default settings all the dates are displayed as labels and there is a overlap of labels on X-axis.

what i want to do is have only three labels on x-axis.
1) at start i.e Min of Dates (the x-axis starts from here)
2) at end i.e Max of Dates (the x-axis Ends here)
3) at the middle (approximately) (between the min and max date)

in Chart wizard, labels can be added to axis manually . but it only accepts INT's.
How can i achieve this with dates?

below is the code generated by the designer while adding labels manually for INT Data types

    
                        Telerik.Charting.ChartAxisItem chartAxisItem1 = new Telerik.Charting.ChartAxisItem();  
        
                        Telerik.Charting.ChartAxisItem chartAxisItem2 = new Telerik.Charting.ChartAxisItem();  
        
                        Telerik.Charting.ChartAxisItem chartAxisItem3 = new Telerik.Charting.ChartAxisItem();  
        
                        chartAxisItem1.Value = new decimal(new int[] {1, 0,0,0});  
        
                        chartAxisItem2.Value = new decimal(new int[] {6,0,0,0});  
        
                        chartAxisItem3.Value = new decimal(new int[] {11,0,0,0});  
        
                        this.radChart1.PlotArea.XAxis.Items.AddRange(new Telerik.Charting.ChartAxisItem[] {  
        
                        chartAxisItem1,  
        
                        chartAxisItem2,  
        
                        chartAxisItem3});

How to change a control between a combobox and a textbox depending on where you call the form?

Hello!!!

I'm using the telerik library, 2008 version. I want to have a unique form that is called from two different options in the menu and depending on the option you select in should show a label and a combobox or a label and a textbox. The label is easy to change, but how do i do to change between the combobox and the textbox? I tried put it over and set the visible attribute to false but it's not working because i have everything inside a table layout and it only lets me put one control in every cell.

Do you have any ideas? Thanks!!

Determine parent or child in CellEndEdit

How can I determine if I'm editing a parent or a child in the radgrid?

I tried something like this:

    
            private void radgrid_CellEndEdit(object sender, GridViewCellEventArgs e) 
        
            { 
        
              Console.WriteLine("cell edit"); 
        
              if (radgrid.Rows[e.RowIndex].ViewTemplate.Parent == null) 
        
              { 
        
                Console.WriteLine(radgrid.Rows[e.RowIndex].Cells[e.ColumnIndex].Value); 
        
              } 
        
              else 
        
              { 
        
                var template = radgrid.MasterGridViewTemplate.ChildGridViewTemplates[0]; 
        
                Console.WriteLine(template.Rows[e.RowIndex].Cells[e.ColumnIndex].Value); 
        
              } 
        
            }

But I'm keep going in the first part of my if statement.

Thanks

Vista/Form Drop Shadow

One of the major issues i have currently with the RibbonBar component is that in order for it to display properly without the standard windows forms title bar, you have to inherit from shaped form, when the forms border disappears, it stops acting like a normal window and no longer drops a shadow on vista. This is a problem becuase the entire reason for using the Ribbon UI is to make the application look like a mature, modern software application, but the window looks badly implemented compared to the other applications running on the system without the form shadow, which somewhat defeats the purpose.

Are there plans to fix this?

RadPlayer.OpenClip( string fileName ) and RadPlayer.OpenClipFromResource( string resourceName ) methods

What is the difference between the RadPlayer.OpenClip( string fileName ) and RadPlayer.OpenClipFromResource( string resourceName ) methods?

I would like to play a byte[] directly, without saving it to file, intermediate or not. I would think that the OpenClipFromResourse method would do the trick (with some preprosessing), but I can't figure out how.

Is there a way to play a byte[] or MemoryStream object?

Regards, Jill-Connie Lorentsen

how to apply theme to gridview

Hi,

I don´t know whether I am missing something but I am not able to apply a theme to my gridview.

If I try to apply "Telerik" theme (I write the following code snippet), the gridview gets crazy and shows a cyan background color.

    
            this.gridView1.ThemeName = "Telerik";

If I write "Vista" theme instead, the theme is applied correctly.

I have checked and among my references is not included "Vista" assembly (Telerik.WinControls.Themes.Vista.dll). I don´t know whtether this is necessary to include. I have aslo tried to copy Telerik.WinControls.Themes.Telerik.dll but didn´t make any effect.

What I am doing wrong?am I missing an asembly?

Thank you in advance.

Patxi.

Visual Studio is attempting to load class instances from a different assembly...

Hi,

I recently updated Telerik to an internal build I needed to fix a RadGridView crash. The internal build I was given consisted of a .zip file with the .dll's. My initial guess was to first uninstall the current Telerik version, then simply copy the dll's in the PublicAssemblies folder of my VisualStudio installation path.

My problem is that when I open a designer, I get the following message

Visual Studio is attempting to load class isntances from a different assembly than the original used to create your components....

The paths shown in the error point to the ProjectAssemblies folder of my Local Settings path. It seems a temporary folder is created there and the .dll is copied there before opening the designer. I tried closing VS and deleting the temporary folders and their 'dll's, but as soon as I restart VS the folders are recreated, the dll's recopied, and the error occurs anew.

What am I doing wrong?
