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());
                        tvNode.ClearSelection();
                        tvNode.DataSource = Globals.dtGMTreeCategory;

                        tvDriver = CloneTreeNodes(tvNode);
                    }
                    else
                        tvNode = CloneTreeNodes(tvDriver);
                    break;

            }
            tvNode.ExpandAll();
        }

                    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:

private void OpenConfigurations()
{
  bsConfigurations.DataSource = Db.Configurations.Where(c => c.Active == true && c.CompanyId == CurrentCompany.CompanyId).Select(c => c).OrderBy(c => c.Name);
  bsConfigurationContracts.DataSource = Db.ConfigurationContracts.Where(c => c.Contract.InsurranceId == CurrentCompany.CompanyId).Select(c =>
c).OrderBy(c => c.Contract.Name);

  GridViewRelation gvrConfigurations = new GridViewRelation();

  gvrConfigurations.ChildColumnNames.Add("ConfigurationId");

  gvrConfigurations.ChildTemplate = this.gridViewTemplate1;

  gvrConfigurations.ParentColumnNames.Add("ConfigurationId");

  gvrConfigurations.ParentTemplate = this.gvConfiguration.MasterTemplate;

  gvConfiguration.Relations.Add(gvrConfigurations);
}

In the designer: 
this.gridViewTemplate1.AllowAddNewRow = false;
gridViewTextBoxColumn1.EnableExpressionEditor = false;
gridViewTextBoxColumn1.FieldName = "Contract.Name";
gridViewTextBoxColumn1.HeaderText = "Name";
gridViewTextBoxColumn1.Name = "colName";
gridViewTextBoxColumn1.Width = 250;
gridViewTextBoxColumn2.EnableExpressionEditor = false;
gridViewTextBoxColumn2.FieldName = "ConfigurationId";
gridViewTextBoxColumn2.HeaderText = "ConfigurationId";
gridViewTextBoxColumn2.IsVisible = false;
gridViewTextBoxColumn2.Name = "colConfigurationId";

this.gridViewTemplate1.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] { gridViewTextBoxColumn1, gridViewTextBoxColumn2 });
this.gridViewTemplate1.DataSource = this.bsConfigurationContracts;
//
// gvConfiguration
//
this.gvConfiguration.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(233)))), ((int)(((byte)(240)))), ((int)(((byte)(249)))));
this.gvConfiguration.Cursor = System.Windows.Forms.Cursors.Default;
this.gvConfiguration.Dock = System.Windows.Forms.DockStyle.Fill;
this.gvConfiguration.Font = new System.Drawing.Font("Segoe UI", 8.25F);
this.gvConfiguration.ForeColor = System.Drawing.Color.Black;
this.gvConfiguration.ImeMode = System.Windows.Forms.ImeMode.NoControl;
this.gvConfiguration.Location = new System.Drawing.Point(0, 30);
//
//
//
this.gvConfiguration.MasterTemplate.AllowAddNewRow = false;
this.gvConfiguration.MasterTemplate.AutoGenerateColumns = false;
gridViewTextBoxColumn3.EnableExpressionEditor = false;
gridViewTextBoxColumn3.FieldName = "Name";
gridViewTextBoxColumn3.HeaderText = "Name";
gridViewTextBoxColumn3.Name = "colName";
gridViewTextBoxColumn3.SortOrder = Telerik.WinControls.UI.RadSortOrder.Ascending;
gridViewTextBoxColumn3.Width = 250;
gridViewTextBoxColumn4.EnableExpressionEditor = false;
gridViewTextBoxColumn4.FieldName = "ConfigurationId";
gridViewTextBoxColumn4.HeaderText = "ConfigurationId";
gridViewTextBoxColumn4.IsVisible = false;
gridViewTextBoxColumn4.Name = "colConfigurationId";
this.gvConfiguration.MasterTemplate.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] { gridViewTextBoxColumn3, gridViewTextBoxColumn4 });
this.gvConfiguration.MasterTemplate.DataSource = this.bsConfigurations;
sortDescriptor1.PropertyName = "colName";
this.gvConfiguration.MasterTemplate.SortDescriptors.AddRange(new Telerik.WinControls.Data.SortDescriptor[] { sortDescriptor1 });
this.gvConfiguration.MasterTemplate.Templates.AddRange(new Telerik.WinControls.UI.GridViewTemplate[] { this.gridViewTemplate1 });
this.gvConfiguration.Name = "gvConfiguration";
this.gvConfiguration.RightToLeft = System.Windows.Forms.RightToLeft.No;
this.gvConfiguration.ShowGroupPanel = false;
this.gvConfiguration.Size = new System.Drawing.Size(1098, 72);
this.gvConfiguration.TabIndex = 4;
this.gvConfiguration.Text = "radGridView1";
this.gvConfiguration.CellDoubleClick += new Telerik.WinControls.UI.GridViewCellEventHandler(this.gvConfiguration_CellDoubleClick);

I think that there is a samo memory leak in  RichTextEditorRibbonBar, so let me show you my very simple scenario:

One empty telerik radform with just one RichTextEditorRibbonBar.

The steps:

1) Show form

2) Close form

3) Show form again

...

The result is new 30-50M in memory on each new form initsialization.

Plese give me some clue to deal with this problem.

Regards,

Simeon

I'm a bit new to the RadControls, and C# in general, so bear with me if the trouble I am facing is due to some terribad implementation. Anyway, here is the problem.

I have a single, form that has a number of radGridViews on it. Most of the grids are very simple lists with a schema that consists of not much more than an 'ID'{int} and a 'Name'{string}. I also have one master grid with a number of GridViewComboBoxColums that reference the aforementioned lists. I'm using entity framework models for the datasources, which I assign using the below

VendorManagerEntities context = new VendorManagerEntities();
 
protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
 
    contactBindingSource.DataSource = context.Contacts;
    statusBindingSource.DataSource = context.Status;
    priorityBindingSource.DataSource = context.Priorities;
    categoryBindingSource.DataSource = context.Categories;
}
Note: The RadGridViews and GridViewComboBoxColums are sharing the same DataSources, a.k.a. I have a grid for status's and a combo box on another grid that both use the statusBindingSource.

When I start the application it populates the grids, columns, and combo boxes from the database; no problem is had. If I then add a row, new value, to one of the Grids that value will show up in the corresponding combobox, but if I select the new value, which apears correctly in the drop down list, the cell will be blank. The correct value is selected, and it submits correctly to the database/model, but it does not display. I suspect that is has something to do with the DisplayMember, but I'm not sure. If I restart the program, and the form is recreated, the new values that were gotten from the database display correctly. What I would like is for the new values to display in their cells, without having to close and restart the form application.

I warn that most of the grid creation was done with the designer, so I am hesitant to post too much of that generated code, but I'll try and get the important bits in here

private void InitializeComponent()
{
this.radGrid_Contacts = new Telerik.WinControls.UI.RadGridView();  // Contacts is "supergrid" that has a ton of combo boxes
this.contactBindingSource = new System.Windows.Forms.BindingSource(this.components);
((System.ComponentModel.ISupportInitialize)(this.buyerBindingSource)).BeginInit();
 
this.radGrid_Statuses = new Telerik.WinControls.UI.RadGridView(); // Status is a simple list, every status wants to some day be part of a combobox
this.statusBindingSource = new System.Windows.Forms.BindingSource(this.components);
((System.ComponentModel.ISupportInitialize)(this.statusBindingSource)).BeginInit();
 
// ...
 
//
// Contact Rad Grid
//
this.radGrid_Contacts.MasterTemplate.AutoGenerateColumns = false;
this.radGrid_Contacts.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
gridViewDecimalColumn1.DataType = typeof(int);
gridViewDecimalColumn1.EnableExpressionEditor = false;
gridViewDecimalColumn1.FieldName = "ID";
gridViewDecimalColumn1.HeaderText = "ID";
gridViewDecimalColumn1.IsAutoGenerated = true;
gridViewDecimalColumn1.Name = "ID";
gridViewDecimalColumn1.ReadOnly = true;
 
gridViewComboBoxColumn4.DataSource = this.statusBindingSource;
gridViewComboBoxColumn4.DataType = typeof(int);
gridViewComboBoxColumn4.DisplayMember = "Name";
gridViewComboBoxColumn4.EnableExpressionEditor = false;
gridViewComboBoxColumn4.FieldName = "Status_ID";
gridViewComboBoxColumn4.HeaderText = "Status";
gridViewComboBoxColumn4.Name = "Status_ID";
gridViewComboBoxColumn4.ValueMember = "ID";
gridViewComboBoxColumn4.Width = 129;
 
this.radGrid_Contacts.MasterTemplate.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] {
gridViewDecimalColumn1,
gridViewComboBoxColumn4,
gridViewCommandColumn1});
this.radGrid_Contacts.MasterTemplate.DataSource = this.contactBindingSource;
this.radGrid_Contacts.MasterTemplate.DataSource = this.contactBindingSource;
 
this.contactBindingSource.DataSource = typeof(VendorManager.Contact);
 
//
// radGrid_Statuses
//
gridViewDecimalColumn6.DataType = typeof(int);
gridViewDecimalColumn6.EnableExpressionEditor = false;
gridViewDecimalColumn6.FieldName = "ID";
gridViewDecimalColumn6.HeaderText = "ID";
gridViewDecimalColumn6.IsAutoGenerated = true;
gridViewDecimalColumn6.IsVisible = false;
gridViewDecimalColumn6.Name = "ID";
gridViewDecimalColumn6.Width = 301;
gridViewTextBoxColumn23.EnableExpressionEditor = false;
gridViewTextBoxColumn23.FieldName = "Name";
gridViewTextBoxColumn23.HeaderText = "Status Name";
gridViewTextBoxColumn23.IsAutoGenerated = true;
gridViewTextBoxColumn23.Name = "Name";
gridViewTextBoxColumn23.Width = 909;
 
gridViewTextBoxColumn24.DataType = typeof(VendorManager.TrackableCollection<VendorManager.Contact>);
gridViewTextBoxColumn24.EnableExpressionEditor = false;
gridViewTextBoxColumn24.FieldName = "Contacts";
gridViewTextBoxColumn24.HeaderText = "Contacts";
gridViewTextBoxColumn24.IsAutoGenerated = true;
gridViewTextBoxColumn24.IsVisible = false;
gridViewTextBoxColumn24.Name = "Contacts";
gridViewTextBoxColumn24.Width = 151;
 
this.radGrid_Statuses.MasterTemplate.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] {
gridViewDecimalColumn6,
gridViewTextBoxColumn23,
gridViewTextBoxColumn24,
gridViewTextBoxColumn25});
this.radGrid_Statuses.MasterTemplate.DataSource = this.statusBindingSource;
this.radGrid_Statuses.Name = "radGrid_Statuses";
 
}


I hope I explained my problem thorougly, if not please tell me so that I can elaborate on anything important that I missed. Thank you in advance for the help.

EDIT: Quite interstingly, if I right click and clear the value on the cell it displays correctly.

I have a from with a number of RadButton elements each of which contains a square Image.

When the application is maximized I want all of the images to remain square when the elements are resized.

Can I re-adjust the sizes after the RadButton elements are resized?

If not, can I lock the aspect ratio of the Images so that resizing the RadButton elements does not distort them?

I am having an issue with the filter option crashing with radgridview.

To reproduce, create a radgridview as I describe below.

Run the program

Quickly click around in the cells of the table a few times, making sure to drag your mouse a bit so to select a few rows on some of the clicks.

Then quickly click the filter. (sometimes takes a few tries)

I get the following error

 

System.NullReferenceException: Object reference not set to an instance of an object. 

   at Telerik.WinControls.UI.GridRowBehavior.DoMultiFullRowSelect(GridCellElement currentCell, Point currentLocation)
   at Telerik.WinControls.UI.GridRowBehavior.DoMouseSelection(GridCellElement currentCell, Point currentLocation)
   at Telerik.WinControls.UI.GridRowBehavior.ProcessMouseSelection(Point mousePosition, GridCellElement currentCell)

   at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context)
   at System.Windows.Forms.Application.Run(Form mainForm)
   at BeaconQuerySource.Program.Main(String[] args)

 

To create the grid do the following.

 Make a RadGridView with the following options (not sure if all are important but the filter and multiselect are) 

this.gridConnectedSessions.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;

this.gridConnectedSessions.MasterTemplate.EnableAlternatingRowColor = true;
this.gridConnectedSessions.MasterTemplate.EnableFiltering = true;

this.gridConnectedSessions.MasterTemplate.MultiSelect = true;

(leave the rest as the default options)

Add 3 columns to the grid

Add 5 rows of data to the grid (I used the following)

radGridView1.Rows.Add("test1","test1","test1");
radGridView1.Rows.Add("test2", "test2", "test2");
radGridView1.Rows.Add("test3", "test3", "test3");
radGridView1.Rows.Add("test4", "test4", "test4");
radGridView1.Rows.Add("test5", "test5", "test5");

 

Any help would be appreciated, thank you.

Hello

I'm actually meeting a problem with Telerik control disposing, using the Q3 2010.3.10.1109.

I joined a screenshot showing an Ant Profiler Analysis, after we disposed manually all our Telerik Controls.

Actually, some RadPropertyValues and others things are not disposed.
Maybe We are doing something wrong while disposing.

Can you pelase tell is where these RadPropertyValues are coming from, and if it's possible to dispose it as all others telerik resources on the screenshot?

For your information, we added dispose() methods for each telerik controls.

Thanks for your lights

This is a question specifically for WinForms but the question is the same as below: 

http://www.telerik.com/forums/radgridview-scroll-position-reset-after-rebind 

Basically, what object and parameters do I have to access within the RadGridView to get my scroll position, so that I can reset it to that position after a rebind.
