Applying alternative themes at runtime

I am using Visual Studio 2008 with VB, using the RadTabControl and RadMenu for my Wind Forms application. I have, thus far, created a theme for each which have a consistent look.

I would like to create a couple of additional themes and provide my users a choice of which themes to apply at run time, for example, with a checkbox in their user preferences form. Each of my forms that has one or more tabs has a RadThemeManager which loads a single theme.
(FYI -- I have never been able to add more than one theme to a Rad Theme Manager without it automatically reverting to the default application theme that ships with your product.)

Can you provide me with a method and some code snippets fo make this possible?

Thank you!

Update Cell Text/value

Hello,

I'm using a button to update a cell value that is in a radgrid. Some times all the cell values of a certain column.

I'm using the following code:

RGFiles.Rows(0).Cells(1).Value = RGProposals.CurrentRow.Cells(2).Value.ToString() & _

"_" & RGProposals.CurrentRow.Cells(3).Value.ToString() & _

"R" & RGProposals.CurrentRow.Cells(4).Value.ToString() & _

"_" & RGFiles.CurrentRow.Cells(2).Value

The code works fine (for one cell) but if I'm updating a cell, i need to pass the mouse over the cell to update the value that is shown in that cell. If I'm updating all cells of a certain column, the cells show the new value but takes a lot of time to do that.

What is missing me? What do I need to do to resolve this problem.

Thank You.
LM

How to set RadMenu Background Image

Hi,
I am evaluating Winforms with VS2008 on XP.

I would like to create a menu strip with rad menu on top and a simple ribbon-style image below the menu. However, when I drag rad menu on top of an existing panel with an image, rad menu does not display the underlying panel image. I have tried setting the rad menu property RadMenu BackColor to Transparent but the rad menu is still opaque and does not display the image.

I must be missing something as I am following the steps in your help documentation on radmenu.

Here are the steps:
1. Start new project with a form.
2. Drag windows panel control onto the form, assign an image to it.
3. Drag radMenu on top of win panel control, enter a menu text item.
4. Select radMenu item and from properties menu, select BackColor property item, then select 'transparent' from the web tab.

Thanks for letting me know wha tI am doing wrong.

saving theme as a resource

Hi, I am evaluating Telerik WinForms - VS2008, XP and
Vista.

I have been testing out the RibbonBar control and have a problem loading the theme file as a project resource. The Telerik theme works fine as a file when it is loaded from a directory on my local machine other than the project resources directory.

However, I would like to keep the theme file in my project resources directory for project portability to be able to load it on other machines. I am trying to create a project template from VS2008 which contains the theme file. After I export my project as a project template the theme does not work (since it is trying to load from a directory on my machine) What is the trick to save the theme file as a resource? Thanks.

Other than this issue the evaluation has gone well and the controls look great.

RadToggleButton Backgrounds

Hi:

I'm creating a list of RadToggleButtons on runtime dinamically, an then I add some events to change their appeareance:

private void bottonDevice_MouseEnter(object sender, EventArgs e)

{

RadToggleButton button = (RadToggleButton)sender;

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)(251)))), ((int)(((byte)(206)))), ((int)(((byte)(117)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor3 = System.Drawing.Color.FromArgb(((int)(((byte)(249)))), ((int)(((byte)(196)))), ((int)(((byte)(52)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor4 = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(220)))), ((int)(((byte)(158)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(232)))), ((int)(((byte)(180)))));

}

The Event MouseEnter changes the Togglebutton background successfully, so the MouseLeave Event too. But the ToggleStateChanged Event simply doesn't work :( here's the Event code.

private

void buttonDevice_ToggleStateChanged(object sender, Telerik.WinControls.UI.StateChangedEventArgs args)

{

// ToggleChange(btnView);

RadToggleButton button = (RadToggleButton)sender;

ToggleChange(button);

if (args.ToggleState == ToggleState.On)

{

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)(254)))), ((int)(((byte)(167)))), ((int)(((byte)(77)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor3 = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(146)))), ((int)(((byte)(0)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor4 = System.Drawing.Color.FromArgb(((int)(((byte)(253)))), ((int)(((byte)(204)))), ((int)(((byte)(116)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(254)))), ((int)(((byte)(197)))), ((int)(((byte)(136)))));

}

else

{

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)(193)))), ((int)(((byte)(193)))), ((int)(((byte)(193)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor3 = System.Drawing.Color.FromArgb(((int)(((byte)(151)))), ((int)(((byte)(148)))), ((int)(((byte)(148)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor4 = System.Drawing.Color.FromArgb(((int)(((byte)(224)))), ((int)(((byte)(224)))), ((int)(((byte)(224)))));

((Telerik.WinControls.Primitives.

FillPrimitive)(button.GetChildAt(0).GetChildAt(0))).BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(226)))), ((int)(((byte)(226)))), ((int)(((byte)(226)))));

}

Can you help me with that issue?. I write my code that way because, I've tried to apply a Theme loaded in design time to my controls, but it didn't work either.

Thanks

Highlighting editable columns

Hi,

These might have already been posted. But I'm posting it again.

1. How do I highlight all the editable columns in the gridview so that the user can easily distinguish editable columns from non-editable columns?

2. How to perform any validations upon the text entered in editable cells when the focus is just lost from that cell (something similar to onfocuslost kind of event)?

3. I need to bind data to the combo box column in the gridview after a button (say a "search" button) is clicked. And I need to extract all the values selected in the grid combo box columns, upon clicking a (say "Submit") button.

Any help would be appreciated.

Thanks
Pramod Goutham.
