I noticed something while testing..

On ItemDataBound event if I have an XML DataSource that has 3 elements
Arrest_Date, Arrest_Agency and MugshotPhoto <--each element calls this event separately.

If I get an XML document that has 9 mugshots the code ends up running through this event 27 times.

Am I not understanding something or is there a better way to do this?

Thanks!

I wish to implement custom behavior on a form with a ribbon bar when the
form is minimised.

It's easy enough to trap the events of the minimise , maximise and close buttons -
However , I am unable to replace these events with those of my own .
In other words I want to be able to implement behavior to the minimise
buttons' click event and stop the minimise button from doing anything else
by default.

I initially looked at the routedeventbehavior class and related classes but cannot
find any code examples on how to use these correctly.

Does the WinForms version of the ComboBox support multi-columns?

I notice that the ASP version does, but there is no mention of this in the WinForms version.

Best Regards
Eddie

Is there a mechanism to change how a selected row appears?  When using a grid with the Office2007Black theme, setting IsSelected or IsCurrent doesn't highlight the row.  The selectionchange event fires properly, but I can see no visual cue which row is selected.

Thanks.

I Have a Grid View. When i right click on the Grid Header and say Conditional Formatting, one Custom formatting Condition Editor Pops up. There we have 4 options, based on the condition we can change the "Cell Back Color", Cell Fore Color, Row Back Color, Cell Black Color "

i want to restrict user from chaning the "Row Fore Color" and "Row Back Color" when user does Conditional formatting.

How can i hide "Row Fore Color" and "Row Back Color" Properties from the Dialog box.

Is there a way i can hide these two properties.

Thanks,
Sasmita

Hi, I have just downloaded the newest version of radControls for WinForms, and it looks + works great!

However, the rightColumnItems are not compatible with Q1 2008 SP1, since I get an error in the designer code at

this

.radMenuItem4.RightColumnItems.AddRange(new Telerik.WinControls.RadItem[] {this.radMenuComboItem1, this.radMenuItem7});

'Telerik.WinControls.UI.RadMenuItem' does not contain a definition for 'RightColumnItems'

I also get a bunch of warnings: 

'Telerik.WinControls.UI.RadMenuItemBase.HasTwoColumnDropDown' is obsolete

When I select the form, I get a message saying:

Error parsing RadItem: Children collection doeas (typo: does) not match - index is not valid radMenuComboItem1 [Telerik.Wincontrols.UI.RadMenuComboItem](1).MenuComboItemBorder[BorderPromitive](1).

In Visual Studio 2005: when I select the menu at runtime I get an error:

Cannot remove the specified item because it was not found in the specified Collection.

How can I change this code to fit Q2 2008?

Thanks in advance.

Hi,

I just downloaded the Q2 Rad Controls. I created a simple windows form application in VS 2008, in C# for testing. Added two GridViews. The left one has theme set to vista (note that nothing visible will happen, not like in the Q1 version where a dark theme was applied). Then from the Property builder I added 3 column for each grid.

issues:
- when applying a theme to the grid, in the VS designer the theme is not recognizable (see picture telerik_theme_color1.jpg, the designer shows a light blue colored square -in background, and the actual theme is nothing like it (black column header and fade-out grid body). So how should I know what am I applying to the application I am working on? It is not a good thing to compile and run the application every time you change a theme, just to see something?
- As you see in pictures telerik_theme_color1.jpg and telerik_coulm_1.jpg, the columns are not visible in the design are in VS. This is also a bad bug like thing.
- after I deleted the columns from the left side Grid (with the Telerik theme), the design view did not change but the hole grid is hidden/not visible while running
(picture telerik_theme_color2.jpg). This issue is probably related to the first issue I mentioned
- minor bug but still unpleasant is that the text "Click here to add new row.." is over the "*"

Thank you

ps. I am using standard stuff: Windows XP with SP2, VS 2008, .Net 3.5, C#, and now the new Winforms Q2 Trial.

Hi,

Like I said in my previous post I am testing (playing with) Telerik so I think I will have a couple of posts/threads here during the following weeks.

I put 2 RadGridViews on my form, and tried to add some columns to it. When I used the Property Builder, it was all good (except the fact that every time I clicked on a column (to delete it or something) it brought up the GeneralColumnSetting panel.. that was a little annoying when you want to add 30 columns and then delete 20 of them afterwards).

Now I tried to add some more columns to the grid from code. Here I started to have some problemes as follows:

1- using this
radGridView1.Columns.Add(myColumn);
or
radGridView1.MasterGridViewTemplate.Columns.Add(myColumn);
has the same efect, and I dont see the difference

2-Setting the column name is tricky:
            myColumn.HeaderText = "test1";
            myColumn.UniqueName = "name1";
            myColumn.FieldAlias = "alias1";
            myColumn.FieldName = "field1";
I found out that this is the order of what will be displayed. So if the HeaderText is not set, then the UniqueName will be set, if that is not set than the Field Alis will be set, and the FieldName is Column name for further referrence. So if the first 3 is not set than nothing will be displayed.

3-After deleting all the columns which I set from the Property Builder, I tried to set columns jut from the code.
Telerik.WinControls.UI.GridViewTextBoxColumn myColumn = new Telerik.WinControls.UI.GridViewTextBoxColumn();
            myColumn.HeaderText = "test1";
            radGridView1.MasterGridViewTemplate.Columns.Add(myColumn);
This simple code will not work, for my suprize (it worked before when I was adding columns to the ones I set before in the Property Builder). So I cheked the code generated by the Property Builder.
Here I found: myColumn.IsAutoGenerated = false;
IsAutoGenerated -cannot be found in the list of Intelisence... not nice.
But even setting everything like in the generated code, I still could not add Columns to my grid (the grid showed no columns at runtime).
I found out that you have to use:
((System.ComponentModel.ISupportInitialize)(this.radGridView1)).BeginInit();
            ((System.ComponentModel.ISupportInitialize)(this.radGridView1.MasterGridViewTemplate)).BeginInit();
and of course the ending part as well to add Columns.
This is very strange, because you don't need to use this in your code (not in the generated one) when you have at least one column added from the Property Builer or added from code but using the "begin init, etc etc" stuff. So after adding at least one (1) Column to the grid you can use the simple grid.Columns.Add() method...

4 - I put two(2) RadGridViews to my form and created a Column like so:
Telerik.WinControls.UI.GridViewTextBoxColumn myColumn = new Telerik.WinControls.UI.GridViewTextBoxColumn();
            myColumn.HeaderText = "test1";
           
and added this to both of my Grids:
            radGridView2.Columns.Add(myColumn);           
            radGridView1.Columns.Add(myColumn);
First thing that I noticed is that it let me do this. Did not complained that I am adding one column to two controls. When I am asking for the owner grid (tru the template) it is the last Grid I added the column to.
The best part is still this: after running the application, when I try to resize the "test1" column in the second grid, it WILL NOT MOVE during the resize, but in stead the "test1" column in the first grid will show the change...spooky :)
The second grid, where I actually changed the column will not show the change until a forced refresh.

I believe that this is not a normal functionality to a grid and or columns.

I hope I get some answers from Telerik people for my posts. Thank you.

Hi, I have already open a thread about this subject but I can´t find it on forums to see if you already gave me an answer, so here go my problem again.

I have a Form, and the form has the keypreview property set to true, so using the Form KeyDown event I close the form when user press Esc Key.

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
            if (e.KeyValue == 27)
            {
                FormCalificacionesRegistro.ActiveForm.Close();
            }
 }

The proble is when I use a RadGridView on the form, when I press Esc Key, I got the error

Objetc Reference not set to an instance of an object, doing reference to my MDI Parent Form called FormMenuPrincipal


static void Main()
{
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new FormMenuPrincipal());
}

Thank you

Hi ,
  we have purchased Telerik License for "RadControls for WinForms Q1 2008" .

    Our requirement is :: Having a Grid with three hierarchies and if there are no rows in chid template, the "+" symbol should not be shown.
    Now ,even if there are no rows in the child template  all rows are preceding with "+".

Is there any specific property setting for the grid to act as per the requirement on our side to get it done or it is not possible with the version we have purchased??

Quick reply is appreciated.
