In place edit auto-highlighting

[John Cornell]

Hi,

I have just begun to test swapping out the Windows default tree view with the Rad one, and I am quite impressed, however, I am lacking one piece of functionality which is very important.

On the Windows tree view, when a begin edit is performed, either by in place clck or programatically, the text is automatically highlighted and the focus is placed in the label.

The rad BeginEdit (bool focus) does not even focus the label, so the label needs to be clicked before a user can type.

Is it possible, programatically, or automatically to have all the text on a label highlighted when a Begin Edit is performed?

Thanks

Hello John,

Unfortunately there is no way currently to highlight the text in the editor on Begin Edit. That will be corrected in the Q2 release for which we are planning big improvements in the editor API.

Hi John Cornell,
We are planning for September, but probably we will come out with BETA sooner.

There doesn't appear to be a TreeControl KB area for me to submit this work around to.

The following code allows for code highlighting and focus on begin edit, and allows the ENTER key to end edit. I appreciate that this may be fixed in Q2 fix, however this is working for me now, otherwise I would have had to swap the control for a default windows one

        //CALL THIS WHEN BeginEdit IS REQUIRED
         private void AllowSelectedNodeEdit()
        {
            if (radTree.SelectedNode != null && radTree.SelectedNode != radTree.Nodes[0])
            {
                radTree.LabelEdit = true;

                //BEGIN THE EDIT BEFORE MANIPULATING THE CONTROL
                radTree.SelectedNode.BeginEdit(true);

                foreach (Control ctl in radTree.Controls)
                {
                    //LOCATE THE RADTEXTBOX
                    if (ctl is RadTextBox)
                    {
                        //IF REQUIRED, SET MODIFIED TEXT HERE
                        ((RadTextBox)ctl).Text = radTree.SelectedNode.Text.Substring
                            (0, radTree.SelectedNode.Text.Length - helper.GetTextSuffix(radTree.SelectedNode.Tag.ToString()).Length);

                        //ADD A KEYDOWN EVENT HANDLER TO CAPTURE THE ENTER KEY
                        ((RadTextBox)ctl).KeyDown += new KeyEventHandler(txt_KeyDown);

                        //SET FOCUS  - THIS WILL AUTOMATICALLY SELECT ALL TEXT
                        ((RadTextBox)ctl).Focus();
                    }
                }
            }
        }



        void txt_KeyDown(object sender, KeyEventArgs e)
        {
            //TRAP THE ENTER KEY - HIDE THE CONTROL TO FIRE THE AFTERLABELEDIT EVENT
            if (e.KeyCode == Keys.Enter)
            {
                if (radTree.IsEditing)
                {
                    if (radTree.SelectedNode != null)
                    {
                        ((RadTextBox)sender).Hide();
                    }
                }
            }
        }

Hi John,

Our KB is not open for editing by the public yet, but I have created a RadTreeView section in our Code Library:
http://www.telerik.com/community/code-library/default.aspx. We have plans to merge the KB with the Code Library to give our clients the ability to edit/add new articles on demand.

Feel free to post your solution using the link above. Once you do so, we will review it and will post it on our site.

Thank you for your involvement in the Telerik community. Your efforts will be rewarded.


Sincerely yours,
Jordan
