Can the validation provider do multiple levels of validation. Example it would be a warning if a number was greater than 2.5 and a hard stop error over 5?

Thanks,

Setting RadGroupBox AutoSizeMode

Hi guys,

I'm in the process of converting all existing WinForm GroupBoxes to RadGroupBoxes programatically. However there's a property called AutoSizeMode that's missing and I need some help to resize a groupbox based on the number of controls in it.

The code that I'm working with now is

    
            GroupBox dbGroupBox = new GroupBox();             
        
            dbGroupBox.Location = new System.Drawing.Point(10, 0); 
        
            dbGroupBox.Name = databaseInstance + pageName; 
        
            dbGroupBox.TabIndex = 0; 
        
            dbGroupBox.TabStop = false; 
        
            dbGroupBox.Text = pageTitle + "  (Possible Matchs)"; 
        
            dbGroupBox.AutoSize = true;         
        
            dbGroupBox.AutoSizeMode = AutoSizeMode.GrowOnly;                         
        
            dbGroupBox.Tag = tag.ToString(); 
        
            dbGroupBox.BackColor = Color.Transparent;

and I need to convert it into

    
            RadGroupBox dbGroupBox = new RadGroupBox(); 
        
            dbGroupBox.Location = new System.Drawing.Point(460, groupBoxY); 
        
            dbGroupBox.Name = databaseInstance + pageName; 
        
            dbGroupBox.TabIndex = 0; 
        
            dbGroupBox.TabStop = false; 
        
            dbGroupBox.Text = pageTitle + "  (Possible Matchs)"; 
        
            dbGroupBox.AutoSize = true;         
        
            //dbGroupBox.AutoSizeMode = AutoSizeMode.GrowOnly;                         
        
            dbGroupBox.Tag = tag.ToString(); 
        
            dbGroupBox.BackColor = Color.Transparent;

Note that line 8 has been commented out because there's no AutoSizeMode in a RadGroupBox. Can you advise on how I can toggle a resize on the Groupbox based on the number of controls within the box? (i.e. the controls are generated dynamically.)

Thanks

RadGridView: Getting Selected Cell within Selected Row

With a RadGridView component, how do I access the contents of a single cell within a row that is selected?

In the code behind, I can access the selected item, but the selection is always the whole row. Granted, this is not unexpected as I have the selection mode set to "Row" (intentionally so). However, when actually interacting with the grid, I can click and highlight individual cells within the row selected – I have to imagine, then, that I should be able to access the specific cell highlighted. To my surprise, I've found no way to accomplish this. Is there a way?

[for context, I want to give the user the ability to copy individual cell values to the clipboard, instead of copying the whole row of values, WITHOUT changing the selection mode]

Fold/UnFold Programmatically

I'd like to have my regions folded when new .CS is loaded.. is there a way to programatically fold / unfold the display text?

Closest thing I could find was this: radSyntaxEditor1.SyntaxEditorElement.FoldingManager.UnfoldAllRegionsContaningIndex(1);

Thanks! Jason

Close items directly from a MdiList?

Hi

I have one of my RadMenuItem having the MdiList set to true and it is working fine, no issues to report here.

Would it be possible to have a way to close one of the child form directly from that menu? Maybe a little X shown on the right like we see elsewhere?

DateTimePicker Focus

I have a windows form in my application which uses the datetime picker. I have noticed that there is no "Focus" property on the control. I cannot do the following:

fromDatePicker.Focus() and force my my user to interact with that control first, other Telerik controls on the form allow me to do this.

I am using the latest version of the WinForm controls and VS 2019

What am I missing?

Thanks

Best Fit functionality

Hi,
I'm trying to use the best fit functionality for ListViews. Im using a list as the datasource like this:

radListView.DataSource = List<Myclass>

and in the BindingCompleted event i do the following:

            foreach (ListViewDetailColumn c in rlv.Columns)
            {
                c.AutoSizeMode = ListViewBestFitColumnMode.AllCells;
            }

The columns are not resized at all. Could you provide me with an example of how to use this feature ?
