RadVirtualGrid is created to support a million records or more. Still it contains some "heavy" operations like CopySelection/CutSelection/Paste which can take a long time.

I would like to intercept these methods so I can show a "Please wait"-window during the operation. Furthermore I have the need to set a flag to true when such a operation is executing.

We can update our extensions to honor the ImplicitUsings settings set globally for new projects. For the item templates, we will need to also check the project settings.

Some other charting frameworks support ‘dynamic’ graphs/diagrams, where the graph shows nodes and links, and the user can drag the nodes around the page, and the other nodes are pulled around it. This is a great way to visualise and explore this kind of node+link data. Its also a great way to sell and app, as it looks cool.

The filter UI controls in ASP.NET Core and MVC are really nice, see filter. Can you include the same controls and UI be included in Winforms and WPF?

Hi everybody

 

I m try use the class CustomDragandDrop on radtreeview but i have a issue, 

if i use the next example, i dont have any problem:

      

   protected void BindRadTreeView()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("Id", typeof(string));
            dt.Columns.Add("Title", typeof(string));
            dt.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string childId = string.Empty;
            for (int i = 0; i < 2; i++)
            {
                parentId = Guid.NewGuid().ToString();
                dt.Rows.Add(parentId, "Node" + i, null);
                for (int j = 0; j < 5; j++)
                {
                    childId = Guid.NewGuid().ToString();
                    dt.Rows.Add(childId, "SubNode" + i + "." + j, parentId);
                }
            }

            this.radTreeView1.ChildMember = "Id";
            this.radTreeView1.ParentMember = "ParentId";
            this.radTreeView1.DisplayMember = "Title";
            this.radTreeView1.DataSource = dt;


        }

 

i can drag and drop correctly

 

but the problem is when i binding the Radtreeview

 

                       

    protected void llenatreeview1() {

            dtTablas = dat.consultaBD();

            DataTable dt = new DataTable();
            dtCopi.Columns.Add("Id", typeof(string));
            dtCopi.Columns.Add("Title", typeof(string));
            dtCopi.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string Id = string.Empty;
            string title = string.Empty;
            foreach (DataRow row in dtTablas.Rows)
            {
                parentId = row["ParentId"].ToString();     

                Id = row["Id"].ToString();
                title = row["Title"].ToString();

                if (parentId == "")
                    dt.Rows.Add(Id, title, null);
                else
                    dt.Rows.Add(Id, title, parentId);
            }

            radTreeView2.ChildMember = "Id";
            radTreeView2.ParentMember = "ParentId";
            radTreeView2.DisplayMember = "Title";
            radTreeView2.DataSource = dt;
        }

first is freeze and then appears the error.

when i drag and drop appears then next error:

System.StackOverflowException

GridView has a default text alignment for new columns as 'MiddleCenter'.

Default alignment for new GridViewDataRowInfo is 'left'.

Please can these be the same ?

It would be nice if the grid column chooser would support grouping of columns similar to the jquery grid

I know that there is a RadRange Attribute but using it creates a dependency on Telerik.

Consider the scenario that the object to be configured via RadPropertyGrid is defined in a library that is used by multiple projects.

I would like to have a generic validation-mechanism, implemented in all controls. Hear me out:

A class ValidationInformation for containing all sort of validation information for a certain field, property, cell, etc. which has properties likes:

  • Type DataType
  • object MinValue
  • object MaxValue
  • int? MinLength
  • int? MaxLength
  • bool IsRequired
  • RegEx Mask
  • etc.

It also has a virtual method like bool Validate(object entity, object value, out string validationError).

A base class ValidationInformationProvider for retrieving validation information from various sources. It has some abstract methods for retrieval, storing/caching information per cell/field/property.

This base class has the following subclasses:

  • ValidationInformationProviderFromDataTable
  • ValidationInformationProviderFromAnnotations
  • ValidationInformationProviderFromXXX

Each provider is responsible for reading validation information from the source (DataTable, annotations on a property, etc.) and fill a ValidationInformation object.

Now the fun begins...

Each Telerik class, like RadGridView and/or subcomponents should get a method or event to retrieve ValidationInformation. When the event is not handled or the method returns null, the default behavior kicks in.

When ValidationInformation is provided, default behavior is overridden. Properties of editors van be set with values from ValidationInformation (like Minimum and Maximum of a GridViewDecimalColumnPlus or RadSpinEditorElement). At the end if editing the method ValidationInformation.Validate is called to validate the new value. The validation error can be used for popups, or tooltips, or an exception. 

This way a user does not have to think where to set which property of any Telerik control for any validation. This way a RadPropertyGrid and RadGridView can work the same way when it comes to data validation, regardless of all editors which work in the background.

Dear Sir,

I’m a retired computer analyst and program for my own enjoyment.

I recently downloaded your UI for Winforms product and played with your Image editor control.

A very nice control indeed. It does some great manipulations of images.

It would be even more flexible if a user were able to add their controls to the radImageEditor control, have access to the loaded image, and be able to add further options to be able to edit images.

Just a thought.

Kind regards

Phil Sargeant
