How to hide the Plus Minus of Root Node only

Hi Telerik,
I just came across an issue and if you can please guide me in this regard.
The issue is that
I want that only the root node (First Node) of tree view dont show its Plus Minus (sign) and it reduce its (only its) indentation as well.
I can see that the property for plus minus is available but that property implements on whole treeview, which is not acceptable to us. And we will need to reduce its indentation as well because if somehow I could be able to hide the plus minus sign the gap between the treeview control border and its first node will look odd.

I hope,I can cleared my point. I wanted to send u the dummy treeview pic to show exactly what I want but i guess attached is not provided this Telerik threads.To understand my application, Its tree view is like that I have One node and all about 100 or so childs and sub childs are under that Single node. So we are looking to hide the Top (Root) node Plus Minus sign and indent the treeview little left to the gap dont look too much.

Looking forward to your quick and helpful response as always.

Regards,
Haroon.

Menu and Toolstrip don't share.

Again, I'm evaluting your controls. On quite a few control sets, you have the ability to share the same object on a menu and toolbar. From what I can tell, you can't not do that on your controls. In other words, I can not make a object that will show up in the menu and toolstrip both.

Also, Am I correct to state that for every object in a menu/toolstrip, it has it's own events that are called. Again, some sets have a common event handler, then you find out what object called the event and process from there.

Thank you

Issue in HtmlViewDefinition

Hi,

I discovered a new issue in the last version of components.

let me show your part of code. (I really cannot provide sample, I have no time for this, I can patch this myself, but perhaps this will help someone)

RadGridView properties in designer code file :

    
            this.RadGridView_Object.AutoSize = true; 
        
            this.RadGridView_Object.MasterGridViewTemplate.AllowAddNewRow = false; 
        
            this.RadGridView_Object.MasterGridViewTemplate.AllowCellContextMenu = false; 
        
            this.RadGridView_Object.MasterGridViewTemplate.AllowColumnChooser = false;

            this.RadGridView_Object.MasterGridViewTemplate.AllowDragToGroup = false; 
        
            this.RadGridView_Object.MasterGridViewTemplate.AllowRowResize = false; 
        
            this.RadGridView_Object.MasterGridViewTemplate.AutoExpandGroups = true;

            this.RadGridView_Object.MasterGridViewTemplate.ShowFilteringRow = false; 
        
            this.RadGridView_Object.MasterGridViewTemplate.ShowRowHeaderColumn = false; 
        
            this.RadGridView_Object.ShowGroupPanel = false;

            this.RadGridView_Object.AutoSizeRows = true;

RadGridView columns definition (pRadGridView is RadGridView_Object) :

    
            // Start update 
        
            pRadGridView.GridElement.BeginUpdate(); 
        
            // Erase content 
        
            pRadGridView.MasterGridViewTemplate.AutoGenerateColumns = false; 
        
            pRadGridView.DataSource = null; 
        
            pRadGridView.MasterGridViewTemplate.Rows.Clear(); 
        
            pRadGridView.MasterGridViewTemplate.Columns.Clear(); 
        
            #region Add columns 
        
            #region Special Column for colorization 
        
            GridViewDataColumn Colorization_Column = new GridViewDataColumn("Colorization", "Colorization"); 
        
            Colorization_Column.IsVisible = false; 
        
            Colorization_Column.HeaderText = "Colorization"; 
        
            pRadGridView.MasterGridViewTemplate.Columns.Add(Colorization_Column); 
        
            #endregion 
        
            /// ADD SOME OTHER COLUMNS 
        
            #endregion 
        
            #region Add Group View Definition

            /// Add colums groups, some columns, two lines 
        
            pRadGridView.ViewDefinition = _ColumnGroupsViewDefinition; 
        
            #endregion 
        
            #region Databind 
        
            foreach(Object item in ListOfObject) 
        
            { 
        
             GridViewDataRowInfo row = pRadGridView.MasterGridViewTemplate.Rows.AddNew(); 
        
             row.Cells["col1"].Value = item.value1; 
        
            // and others 
        
            } 
        
            #endregion 
        
            // End of update 
        
            pRadGridView.GridElement.EndUpdate(); 
        
            // Best fit columns 
        
            pRadGridView.MasterGridViewTemplate.BestFitColumns();

Ok, run this and what appends....

The first issue is that the two header rows are not displayed, only the first one.
Anyway, just click on first DataRow, the second Header row is diplayed but First DataRow is behind... Wow

So, the only one solution for me, was to set this.RadGridView_Object.AutoSizeRows = false;

hope this will help.

Best regards

EDIT : this issue is for ViewDefinitions and not only Html one. Sorry.

How can I populate a series of textboxes when I click on a row in the GridView?

I have a WindowsForm App that shows a list of users using RadGridView .
When you double click on a row on the GridView I pop up a second form containing textboxes.
I am trying to populate these boxes with the data from the selected row of the GridView.
I tried to use FindControl but that doesn't seem to work.

Does anyone have a piece of code in VB that will make this work?

Thanks

RadComboBox always defaults to first row

Hi,
I have a RadComboBox which always stays focused on the first row. The list is a list of contacts and I bring back contacts for a specific customer. However there is a problem with SelectedItem, as the value is saved but when I reopen the form the combobox still defaults to the first row. Any ideas?

Thanks.

BoxLayout and positioning

Hi,

I have a control which inherits from RadTextBox

The layout should be the following, (a textbox with a button on its side and a couple of labels)

___________________________________________________

| TextElement TextElement |

|__________________________________________________|

|_TextBox ________________________________|_Button_|

Problem is I cannot get the textbox and button to lay out in the correct order. The button is always rendered to the left and the textbox to the right, any way to change this?

Thanks,

/ jorge

To Disable Column Drag and Drop

Hi,
We are using WinForms Q1 2008 SP1 RadGridView.
The problem we are facing is that even though we have disabled drag drop of the columns in the grid, if the user tries to drag any column header outside the form or within the grid other column and wait for few seconds (>= 5 Sec) , following runtime error is coming
object reference not set to instance of an object.

What we are trying to do is disable column drag and drop of grid columns, I have already tried MasterGridViewTemplate.AllowDragToGroup = False , column chooser , column reorder everything false.

Note : we are having timer tick event set for 5 seconds which refreshes the grid every after 5 sec.
if we remove timer event , above problem gets resolved.

Even we dont want effect of drag and drop.

We need solution for this with timer enabled ASAP.

Please help.

Regards
Vishal

Inheriting RadTextbox with Multiline problems

Hi,

I am upgrading from an old solution, see http://www.telerik.com/community/forums/winforms/ui-controls/labelmultilinetextbox-with-validation.aspx, since this version is missing some functionality which I now need.

My class inherits from RadTextBox where I override CreateChildItems and create my own.

I follow the logic from your source and it all works perfectly. Except the multiline property, how can I implement it?

I use the following controls.

private readonly RadTextBoxItem textBox = new RadTextBoxItem();

private readonly TextPrimitive title = new TextPrimitive();

private readonly TextPrimitive validation = new TextPrimitive();

A cut down version of CreateChildItems

BoxLayout layoutTexts = new BoxLayout();

layoutTexts.Orientation = Orientation.Horizontal;

layoutTexts.StretchVertically = false; // when true the control is drawn differently

layoutTexts.Children.Add(title);

layoutTexts.Children.Add(validation);

BoxLayout layout = new BoxLayout();

layout.Orientation = Orientation.Vertical;

layout.Children.Add(layoutTexts);

base.InitializeTextElement();

layout.Children.Add(textBoxElement);

RootElement.Children.Add(layout);

Size = new Size(425, 34); // default size

Thanks
