Problem with button in WinGrid

Richard posted over 12 years ago

Hello,

I am having trouble with two buttons I inserted in a WinGrid. I added the two buttons side by side and they show correctly when I run the program but if i scroll to the right to see more columns and then scroll back to the left, the buttons overlap.

I would like some help to resolve this. Please see the image below:

Thank you.

Hello RichSee,

Thanks for attached sample. I saw your issue, but the mentioned behavior is expected because your are using :

newButton.Rect =new Rectangle(33, 25, 70, 26); instead of my code:

newButton.Rect = new Rectangle(El.Rect.X +El.Rect.Width - 20, El.Rect.Y, 18, 18);

By this way you will get two different issues:

1. when you scroll your grid, the button will keep always his position

2. you will get issue with redraws of your control.

Please take a look at the attached video for more details and use my suggestion from my sample. Let me know if you have any questions.

Regards

Hi Georgi,

I looked at the sample you sent using the CreationFilter and modified it as little as I could by just adding one button. After adding the one button I got the same behavior I get in my project. Please take a look at the sample code that was modified.

Thank you.

Hi Georgi,

I have taken a look at the code sample you provided. Sorry for the late reply.

I was unable to reproduce the scenario using our code but it is very similar to the code you provided.

I will provide code that we are using to create the two buttons in one cell:

public class CreationFilter : IUIElementCreationFilter

{

public void AfterCreateChildElements(Infragistics.Win.UIElement parent)

{

if (!(parent is HeaderUIElement))

return;

// get the associated column

UltraGridColumn column = parent.GetContext(typeof(UltraGridColumn)) as UltraGridColumn;

if (column == null)

{

return;

}

else

{

if (column.Key == "KEYNAME")

{

int widthCenter = parent.RectInsideBorders.X + (parent.RectInsideBorders.Width / 2);

int heightCenter = (parent.RectInsideBorders.Y + ((int)((double)parent.RectInsideBorders.Height / 2)) - 10);

// create a new button element

ButtonUIElement buttonNew = new ButtonUIElement(parent);

// hook into its click event

buttonNew.ElementClick += new UIElementEventHandler(this.OnCustomButtonClick);

Rectangle buttonRect = new Rectangle();

buttonRect.Width = 70;

buttonRect.Height = 26;

// set the button element's rect-

buttonNew.Rect = buttonRect;

buttonNew.Text = "BUTTON_NEW";

parent.ChildElements.Add(buttonNew);

buttonNew.Rect = new Rectangle(widthCenter / 2 - ((widthCenter / 2) / 2), heightCenter - ((int)((double)(heightCenter / 2))), buttonRect.Width, buttonRect.Height);

// create a new button element

ButtonUIElement buttonDelete = new ButtonUIElement(parent);

// hook into its click event

buttonDelete.ElementClick += new UIElementEventHandler(this.OnCustomButtonClick);

Rectangle buttonRect2 = new Rectangle();

buttonRect2.Width = 70;

buttonRect2.Height = 26;

// set the button element's rect

buttonDelete.Rect = buttonRect2;

buttonDelete.Text = "BUTTON_DELETE";

parent.ChildElements.Add(buttonDelete);

buttonDelete.Rect = new Rectangle(widthCenter + ((widthCenter / 2) / 2), heightCenter - ((int)((double)(heightCenter / 2))), buttonRect2.Width, buttonRect2.Height);

}

}

}

}

-Thank you-
