[Solved] RadButtonElement subclass doesn't have correct style

If I subclass RadButtonElement, the subclass no longer has the same style applied as a pure RadButtonElement. Here's the simple code snippet:

                                ...         
                        panel.Children.Add(new RadButtonElement() { Text = "RadButtonElement" });         
                        panel.Children.Add(new MyRadButtonElement() { Text = "MyRadButtonElement" });         
                    }         
                     
                    class MyRadButtonElement : RadButtonElement         
                    {         
                    }         
                     
                     

Can you tell me how to make my RadButtonElement have the same default style (e.g. background color, mouse rollover) as a regular RadButtonElement?

Thanks,

Simple insert, update, delete in Grid

Hi again!

Today I was looking for an Solution to update, insert and delete rows in a grid without a Dataadapter.
I found a few threads, but in the most you told us to wait for the next Version of RadGrid an new Handling of events. (My actual version is Q1 2009)

I need a solution where I can user my own statements and parameters in a Radgrid.
I fill the grid with:

    
            RadGridView1.MasterGridViewTemplate.LoadFrom(reader)

I was logging the RowsChanging and RowsChanged events, but cannot find the right solution for my problem
For example: When I add a new row, the rowChanging event fires with e.action = Telerik.WinControls.Data.NotifyCollectionChangedAction.Add but then no Changing events with Telerik.WinControls.Data.NotifyCollectionChangedAction.ItemChanged is fired for this row

Then I tried to use the CellEndEdit- Event but cannot find a way to know that I'm in a new Row and so on...

Pleas help.

regards
Willi

Check/uncheck all checkboxes of childstemplates

Hello,

Okay I've got a gridview that has 2 levels: parent, child.

Now in both levels I've got a checkbox column.

So I want to check/uncheck all checkboxes in the child level when I clicked on the parent his checkbox.

I got it working I thought but I'm getting some strange behavior. I think I know why, but I have no idea for the moment how to solve it.

okay my code snippet:

                    private void rgvAdserverNetwork_ValueChanged(object sender, EventArgs e)         
            {         
                var cell = sender as GridDataCellElement;         
                if (cell == null || ((GridViewDataColumn)cell.ColumnInfo).FieldName != "Add") return;         
                         
                var viewTemp = cell.ViewTemplate;         
                var tempRow = cell.RowElement;         
                var rowinfo = tempRow.RowInfo;         
                         
                if (!(bool)cell.Value)         
                {         
                    //loop the child items to set the checkbox to true         
                    loopChilds(rowinfo);           
                    rowinfo.Cells["Add"].Value = true; //set the checkbox of the parent to true         
                }         
            }         
                     
            //loop the child items of the given master row         
            private void loopChilds(GridViewRowInfo masterrow)         
            {         
                var childRows = masterrow.ViewTemplate.ChildGridViewTemplates[0].GetChildRows(masterrow);         
                if (childRows == null) return;         
                var length = childRows.Length;         
                     
                var expandedState = masterrow.IsExpanded;         
                masterrow.IsExpanded = true;         
                     
                for (var i = 0; i < length; i++)         
                {         
                    childRows[i].Cells["Add"].Value = true; //set the checkbox of the parent to true         
                }         
                masterrow.IsExpanded = expandedState;         
            }         

Maybe there is a better way to achieve this.

Thanks a lot in advanced.

ToolBoxInstaller Failed on RadControls install

Hi all,

I tried installing RadControl for WinForms Latest Version: 2009.1 311 (Mar 11, 2009) . My OS is WinXP SP2, and Visual Studio 2008 Pro Version 9.0.21022.8 RTM, .Net 3.5 SP1. I remember I had a problem with installing RadControl for ASP.net, and was able to install the tools into the toolbox manually. My skill level: know just enough to break something.

How do install RadControls for Winform manually, here is a copy of the installer log below.

Thanks,
David

Right Click menu

is it possible to edit this to allow us to add our own menu items?

also is there an event fired when rightclick happens? i need to check some values outside the sched before allowing access to right click menu

basically i was hoping to use this control to allow admin users to create date range events for a holiday booking website (basically assigning rates & availabilities) where they select the number of days they want. you then right click to get menu to allow you to opens my own popup screen where the user enters the the rates and availability for that date range and then saves. when the form closes then the scheduler will refresh/update with these details

am i asking too much of the control?

Cheers.
Craig

[Solved] Hierarchy relation problem?

Hi,

I'm trying to display a 3 level hierarchy into the gridview. I have no problem when I have a 2 level hierarchy. With the 3 level hierarchy I only get the first 2 levels. Now I guess I'm doing something wrong in the relations. But I can't seem to find the mistake or is it something else?

My code:

                    //add columns and relations         
            rgvAdserver.MasterGridViewTemplate.Columns.Add(new GridViewDataColumn { FieldName = "SiteId", HeaderText = "Site Id", HeaderTextAlignment = ContentAlignment.MiddleCenter });         
            rgvAdserver.MasterGridViewTemplate.Columns.Add(new GridViewDataColumn { FieldName = "SiteName", HeaderText = "Site Name", HeaderTextAlignment = ContentAlignment.MiddleCenter });         
                     
            var template = new GridViewTemplate { AllowAddNewRow = false, AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill };         
            template.Columns.Add(new GridViewTextBoxColumn { FieldName = "SiteId", IsVisible = false });         
            template.Columns.Add(new GridViewTextBoxColumn { FieldName = "ZoneId", HeaderText = "Zone Id", HeaderTextAlignment = ContentAlignment.MiddleCenter });         
            template.Columns.Add(new GridViewTextBoxColumn { FieldName = "ZoneName", HeaderText = "Zone Name", HeaderTextAlignment = ContentAlignment.MiddleCenter });

Installing RibbonForm Template

I have been trying to install the Q1 2009 templates for the windows form controls. I have followed exactly what the KB article says at http://www.telerik.com/support/kb/winforms/general/installing-telerik-templates-in-visual-studio-2008.aspx, but the templates are not showing when I try

to do a new project. Can anyone shed some light on here as to what I may be missing?

Also, all of this started because I wanted to use the RibbonForm as my starting form. But the problem there is that the default Application.Run won't work

because RibbonForm does not inherit from Windows.Form. So, can someone tell me how to execute and start my applicaiton without this inheritance?

Thanks in advance,

LK
