I want to let the user to color some words or phrases in a Textbox.

I thought the features of RadTextBoxControl would be good for that. (In between RadTextBox and RichTextEditor)

First handicap, I seem to have no influence on Block Creation, meaning on how the text is split into Blocks.

Than I assign a text like 'Dvoraks "New World" Symphony'

I get Blocks like

• Dvoraks
• "New
• World"
• Symphony

Not really what I wanted.

I found no other way than this:

Is this a good way, the recommanded way, to do custom splitting ?

Next: I could not attach a click event to a text block.

I found your Demo with a Button inside a TextBox (implementing ITextBlock on RadButtonElement) this works fine.

But something like this, is just never called (replacing the "new TextBoxElement" with "new TBE" in the above snippet of course)

 

Than I tried to subscribe to the Click-Event directly. (The Click Event of the TextBlockElement). No catched event either.

Another try:

 

No success either: The GetElementAtPoint always returns the TextBoxElement, which is not wrong, but I want a children of it, a TextBlock.

 

So I need help on how to catch a click on a TextBlock,... than finally I can color my Block on user click (with setting textblock.ForeColor = Red f.e.).

 

Finally, what I'am missing also is Selecting a TextBlock. The Select Functions of TextBoxControl are all character based.

But has the TextBlock information about it's own position in the whole Text ? Is this the Offset/Length Property  ? Documentation don't gives me any clue, if this is something measured in pixel, number of characters, or whatever.

So how do I something like textBoxControl1.Select(textblock) ?

 

 

 

 

Successful to get the button into header cell for expanding/collapsing the group columns except last one (this is sum of the reaming  columns since should not be collapsed) in each group.

This has been achieved by creating button in header cell through  radgrid CreateCell event.

But failed to achieve couple of below things,
Refer attached screenshot, expand/collapse button must be placed in title of the group, marked 1 in attached image. New position should be marked  in second image.
Button image must be changed, meaning while expanding, there is should be one image ,when collapsing there should be another image.
(Have tried this, but it is behaving strange, button image is getting changed in different position, seems it is redrawing )

Appreciate, if somebody could help us to accomplish this

Hi!

I need help to use our custom DropDownPopupForm (custom means that we have items in the list and after the DropDownListElement we have one RadButtonElement) for auto completion feature too.
Our custom DropDownList works as expected, when I click on the downward arrow then it shows our customized DropDownPopupForm, but when I start typing into the DropDownList then suggestions are not formatted the same way as in the previous scenario (they are not formatted at all).

I found that the AutoCompleteSuggestHelper class has the following line:
"internal bool isSuggestMode = false;//indicates this as Suggest DropDownList e.g. this is a second drop down"

So if I try to use our custom DropDownListElement, then I can not set this field from outside the package.

 

Thank you,
Sandor

 

 

I've been trying for 2 days now to download the latest QuickStart app, the one with the infamous MainForm, and have been unsuccessful.  It seems there's many versions of this, most of which I found in forum threads. 

The last one I got is "079906_QSF".   A number of erros come up when I try to build it, so it won't even build, and it does have the MainForm, but it won't even open in VS. 

Also, I noticed this QSF project/solution is in C#.  I primarily use VB.  So does a VB version of this QuickStart/Example app exist?  I'm very curious to understand how that MainForm was built. 

Thank you much for your time,
Daniel


Here's some of the errors when I try to build the project:

I wrote some code to capture the user's selected values before changing them. Thus, allowing the changes to be restored to the previous values. 

The problem I ran into was that my click event from the contextmenu is called multiple times. This wipes out the true previous values. I could just add a flag at the beginning of the event, but I was wondering if there was a better way to approach this? why is this click event called multiple times on a single click?

 

Line 11.  _lastGridChange saves the values before they are updated

 

 

 

Setting up the ContextMenu Options

 

 

 

 

 

The link for Navigation - Context Menu opens the "Menu" page and not the "Context Menu" page. 

 

 

I have RadGridView with GridViewColorColumn . The default color picker dialog is far more advanced than what i need. I just need to allow user to pick basic colors. I see a ENUMS in RadColorDialog  class such as ShowBasicColors, ShowSystemColors, ShowWebColors, ShowProfessionalColors. 

Question is, how do i modify this behavior from Grid?

 

i need to show only basic colors.

 

please help.

 

 

Hi, 

 

The ability to add a heirarchy to the parent rows in the virtual grid is great, but is there a way to add multiple data types for the children rows?

 

For example 

 

public class Parent{

public string Name = "Parent Row";

public ChildType1 child1 = new Child1();

public ChildType2 child2 = new Child2();

 

}

 

When a user expands the Parent row, is there a way to define new grids for both Child1 and Child2 to be expanded?  This would be super helpful for an asset management project I'm working on. 

 

Thanks,

Mike

how can i prevent the group from collapsing ?

best thanks 

Hello,

I have two RadGridView bound to two different Lists, on two different tabs of a tab control; I DeferRefresh, set the data source, set AutoSize columns mode to none and then call BestFitColumns

The second grid, containing just two example rows, gets its columns resized as expected, but not the first that looks like nothing happened.

The strange behavior is that, if I manually resize (aka click the corner of the window and drag) even just of some pixels the WinForm where the tabs and the grids are staying, the columns gets refreshed to the best fit, as expected from the BestFitColumns command, somehow like it was not refreshed after the bind. This grid have 60 rows, not so many, both Lists contains the same class, so the amount of columns is the same; both grids have the same attributes.

Any idea?

Thank you in advance

Best regards
