I have a form which contains TreeView control. I need to convert it to RadTreeView. So I replaced TreeView control with RadTreeView and TreeNode with RadTreeNode in the code. I found that the events in both are different, so tried to replace the events with similar events in RadTree.

Following are the events that I have replaced in my code :

1.  

        Private Sub TreeView1_AfterExpand(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvMain.AfterExpand

Replaced by -

        Private Sub TreeView1_AfterExpand(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.RadTreeViewEventArgs) Handles tvMain.NodeExpandedChanged   

2.

            Private Sub TreeView1_AfterCollapse(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvMain.AfterCollapse

  Replaced by -  

            Private Sub TreeView1_AfterCollapse(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.RadTreeViewEventArgs) Handles tvMain.NodeExpandedChanged

and included Expanded flag to check if it is expand or collapse.

Here, I noticed unwanted firing of this replaced event when compared to the old event, but I handled it using the Expanded flag.

3.

        Private Sub tvMain_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvMain.AfterSelect

Replaced by -

        Private Sub tvMain_AfterSelect(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.RadTreeViewEventArgs) Handles tvMain.SelectedNodesChanged

This event gets fired twice while clicking on a node.

My main issues are,

  • During the initial load of the form, the tree gets populated and at that time the select event (mentioned in point 3) fires automatically in my old project in which TreeView is used. But in the new project, during the load of the form the replaced event is not fired.
  • Similarly, when I clicks a node , the replaced select event fires twice. After that I have a button in the same form which works like, when we click on a node and then click on the add button it will add a new node to the tree under the selected node. Now the functionality of the button doesnt work because, within the click function of add button, treeView1.selectedNode is 'Nothing'. Eventhough the select event is fired on clicking the node, the selectednode is 'Nothing' inside the click function of add button.

Within the CellEndEdit event, the GridViewCellEventArgs should contain an item to Cancel/Undo which will revert the value of the cell back to the value it had when CellBeginEdit was called.

Dear,

I wonder if it is possible to consult the release history by product & control & version, next to the (already existing) release history by product & version & control?

This feature has benifits:

  • see how a given control evolves in time
  • quickly find if a bug/feature has been implemented by control

This request can be applied for all your products.

Kind regards,

Peter

Hi there,

 

We have recently found a bug on both the RadDocument and Rad Rich Text Editor. Created a RTF document via the RadRichText Editor. The RTF document contains a table. When the document is saved and loaded from the same form, it is displaying correctly, however when loaded from a different form, it seems to have shrunk and lost the column width, thus having long and skinny columns.

We have set the fixed column width on the table, however this did not seem to solve the issue.

I have attached two screenshots for reference. One with the correct looking table, and one with the long and skinny columns.

Is there a workaround, or is this a known bug?

 

Correct table:

 

 

Long and skinny columns:

 

Currently on Telerik Winforms version 2018.3.1016.40

 

Kind regards,

Paul

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

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 Peggy,

 

It sounds a bit too complicated for the pre sales engineer. Can you please kindly let me know the license holder email and I will issue a support ticket on his Telerik account so that the developing team can get involved.

Hi Peter,

我們在跟一個客戶討論續約問題,因為如果不續約,當下的版本是否可以一直沿用,因為這套軟體升級不會刪除舊檔案,導致很多問題出來。

 

因為客戶編輯好專案,也進行發行動作,但是安裝到電腦會發生錯誤,請問要在其他台電腦執行客戶的安裝該如何執行.

請回復技術問題.

Hi All,

 

I have made User control for custom node, in this user control i have used following controls

1 RadLabel (no of control - 3)

2 RadPanel (no of control -1)

3 PictureBox (no of Control - 4 )

4 TableLayoutPanel (no of control -3)

Means i have used total 11 controls within my user control.

Height of usercontrol = 146

Width of Usercontrol = 595

 

I have taken RadTreeView and above UserControl added as Node,following properties of treeview is set

this.radTreeView1.DataSource = Staff.GetStaff();
            this.radTreeView1.ParentMember = "ParentID";
            this.radTreeView1.ChildMember = "ID";
            this.radTreeView1.DisplayMember = "Department";
            this.radTreeView1.CreateNodeElement += this.OnCreateNodeElement;

this.radTreeView1.TreeViewElement.AutoSizeItems = true;
            this.radTreeView1.ShowRootLines = false;
            this.radTreeView1.FullRowSelect = false;
            this.radTreeView1.ShowLines = true;
            this.radTreeView1.LineStyle = TreeLineStyle.Solid;

            this.radTreeView1.TreeIndent = 50;

this.radTreeView1.ExpandAll();

 

But when i run the code it shows like this means my control is not displaying and the property "AutoSizeItems" is not working.

 

hope for quick reply
