Hi,

 I've gone through this page and have a few questions:

 http://www.telerik.com/help/winforms/gridview-populating-with-data-unbound-mode.html

---------
Reason for using Unbound Mode: I'm building a Multi-threaded application, this application has several slow processes in the background and each of them returns a value. I use these values to fill cells in a gridview one by one without blocking the rest of the user interface. I've got this working quite well and happy with the result. I couldn't have done this with binding (this would have resulted in constantly fully reloading the gridview, now I just modify each cell when needed). This is the reason, why I'm using unbound mode.

---------

Now, for my next modification - I need a hierarchy in the gridview and I'm having trouble getting this to work:

I need something like the following:

Now, when following the steps for "hierarchical grid in unbound mode" I'm getting way too many child rows. I believe the reason for this is because I'm using a template like so:

Then I loop through the amount of childrows that need to be created like so:

This results in having way too many childrows. I've just taken two random columnnames as the relationship => I'm assuming this is probably the reason why things aren't working.
The thing is, in my case there is no real relationship between child and parent. The parent is just the average values of all children. Does this mean I need to create an extra column just for the sake of the relationship ?

Also, when using unbound mode (in a non-hierarchical situation) I first create the rows, and then fill them. If in hierarchical mode, I'm getting the impression that I can't create the childrows without filling them (not sure)?

All I really want to do, is create child rows an fill the cells one by one, whenever I can....

Thanks in advance for the help and example !

Hello,

We habe to implement a graphical tour planning.

One line for each employee and all tasks on the timeline.

                           10:00-----------11:00--------------12:00---------------13:00

Employee 1.                /------Task1-----/. /-------Task 2-----/

Employee 2.                        /---Task1--/ /---------Task2--------/ /--Task3---/

Is there a way to do this with RadGanttView ?

 Thanks in advance

Hello,

Very good to hear that the RichTextEditorRibbonBar localization provider came out.

Where can I find the RichTextEditorRibbonBar localization file.

Thank you...

I have a grid view with several columns set where AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill.  I do have few columns with a fixed width (i.e. MinWidth = MaxWidth = Width).  This is working fine as you can see in picture Gridview1.  The gridview has the following properties:

this.RadGridViewTansBancaire.MasterTemplate.AllowAddNewRow = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowCellContextMenu = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowColumnChooser = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowColumnHeaderContextMenu = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowColumnReorder = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowDeleteRow = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowDragToGroup = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowEditRow = false;
this.RadGridViewTansBancaire.MasterTemplate.AllowRowResize = false;
this.RadGridViewTansBancaire.MasterTemplate.AutoExpandGroups = true;
this.RadGridViewTansBancaire.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;

Now, whenever I group these columns into 2 groups, the fill command is not working anymore as shown in picture Gridview2.

I tried several things, read the posts and the actual commands used are:

RadGridViewTansBancaire.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.None;
ColumnGroupsViewDefinition columnGroupsView = new ColumnGroupsViewDefinition();
columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup(Offix.Culture.Traduire("BANQUE", "BANK")));
columnGroupsView.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[0].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["BankDescription"]);
columnGroupsView.ColumnGroups[0].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["BankReference"]);
columnGroupsView.ColumnGroups[0].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["BankDate"]);
columnGroupsView.ColumnGroups[0].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["BankMontant"]);

columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup("OFFIX"));
columnGroupsView.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixJournal"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixNoJournal"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixDate"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixCode"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixNom"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixType"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixReference"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixNoDocument"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixDebit"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["OffixCredit"]);
columnGroupsView.ColumnGroups[1].Rows[0].Columns.Add(this.RadGridViewTansBancaire.Columns["Verifie"]);

RadGridViewTansBancaire.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
RadGridViewTansBancaire.BestFitColumns();

hi ,

how can I remove all the boarders of toggleswitch and I want to change its value only by dragging not by clicking. Is it possible?

Hi;

I detected a problem when displaying an alert RadDesktopAlert and select up in the direction of the animation, The control appears outside desktop.

Using other direction out of the alert is resolved, but not what I want, I want you to act as in previous versions with the up direction.

I attached a project where you can see the error perfectly

Hi there,

I was wondering if it was possible to modify the start menu of the RichTextEditorRibbonBar. Ideally I would like to clear all the items and add my own. However, from my experiments, this is not possible.

Is there a way to achieve this without manually creating a RibbonBar and re-create all the text formating operations?

Thank you

Hi

Please advise how i can clone a tree view

I have a radDropDownList and a RadTreeView.

upon selection in the drop down, my data chages, though the table structure remain the same. Suppose i have options 1 and 2 in the drop down. user selects option 1 and tree is populated. User makes some selections in tree check boxes, then select option 2 from drop down list, new data populateed in tree view, and user does further selections in tree view. Now user goes back to option 1, i should get the tree view with data and tick selections

 below are my codes, but this does not seem to be good. tvNode is in designer

local variables

        RadTreeView tvAsset = new RadTreeView();
        RadTreeView tvDriver = new RadTreeView();

        private void cbStruc_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
        {
            if (cbStruc.SelectedItem == null)
                return;

            int i = 0;
            Image imagetemp;
            switch (cbStruc.SelectedItem.ToString())
            {
                case "Assets":
                    if (tvAsset.Nodes.Count == 0)
                    {
                        TreeView tv = new TreeView();
                        new GroupMatrix().PopulateTreeCategories(tv, Globals.uLogin.lMatrix, cbStruc.SelectedItem.ToString());
                        tvNode.ClearSelection();
                        tvNode.DataSource = Globals.dtGMTreeCategory;

                        tvAsset = CloneTreeNodes(tvNode);
                    }
                    else
                    {
                        tvNode.ClearSelection();
                        tvNode = CloneTreeNodes(tvAsset);
                    }
                    break;

                case "Drivers":
                    if (tvDriver.Nodes.Count == 0)
                    {
                        TreeView tv = new TreeView();
                        new GroupMatrix().PopulateTreeCategories(tv, Globals.uLogin.lMatrix, cbStruc.SelectedItem.ToString());

                    }
                    else
                        tvNode = CloneTreeNodes(tvDriver);
                    break;

            }
            tvNode.ExpandAll();
        }

    private void cbStruc_SelectedIndexChanging(object sender, Telerik.WinControls.UI.Data.PositionChangingCancelEventArgs e)
        {
            if (cbStruc.SelectedItem != null)
                switch (cbStruc.SelectedItem.ToString())
                {
                    case "Assets":
                        tvAsset = CloneTreeNodes(tvNode);
                        break;

                    case "Drivers":
                        tvDriver = CloneTreeNodes(tvNode);
                        break;

                }
        }

        RadTreeView CloneTreeNodes(RadTreeView tvFrom)
        {
            RadTreeView treeview2 = new RadTreeView();
            if (tvFrom.Nodes.Count == 0)
                return treeview2;

            foreach (RadTreeNode tn in tvFrom.Nodes)
                treeview2.Nodes.Add((RadTreeNode)tn.Clone());
            
            treeview2.DataSource = tvFrom.DataSource;
            return treeview2;
        }

Kindly advise

Thank you

I have created a hierarchical relationship in a RadGridView. But the relationship doesn't work. I can't show the detail information. What do I do wrong?

This is the source:

c).OrderBy(c => c.Contract.Name);
