Apply changes to GridStyleInfo

[Terence Rossow]

Hi there,

I am trying to apply the changes from one GridStyleInfo to another. The situation is that I have a toolbar which modifies a GridStyleInfo drawn from the current selection of cells, after which it fires an event which is caught to update the styles in the grid (by firing the SaveCellInfo event). I am only interested in changed properties - if a user clicks bold, I simply want to apply bold formatting to each selection, without destroying their existing formatting. If the user removes a top border, I simply want to remove that top border from the selections.

I think that I should be using the GridStyleInfo.ModifyStyle function - however I am having a hard time understanding it''s behaviour. I had thought that StyleModifyType.Changes was the one I needed - but it appears to only add properties that have changed - doesn''t change existing ones or remove remvoed ones. Is this correct?

If anyone can help it would me most appreciated.

Cheers,

Here is exactly what I want to do:

Given a source and target GridStyleInfo (source comes from a control that modifies the style of a selection, and target is the style used by the grid), if the source has a value for a property, copy that to the target (regardless or whether the target has a value for the property or not). If the source does not have a value for a property that the target does, remove that property value from the target.

Hi Haneef,

Thanks for the reply.

What I am actually after here is the exact behaviours of the GridStyleInfo.ModifyStyle function for each of the StyleModifyType enumeration values. The documentation is a little vague, and my own tests of the function have not made it very much clearer to me.

Thanks,

I have a specific example of my confusion here:

I have a GridStyleInfo object that applies to a cell in the grid (theCellStyle):

{Interior = Pattern; None; WindowText; 255, 204, 0
Format = "#,##0"
Borders.Top = Solid; Black; ExtraThin
Borders.Bottom = Solid; Black; ExtraThin
VerticalAlignment = Middle
ShowButtons = ShowCurrentCell
}

I then have a style that will be applied to the row that the aforementioned cell is in (theRowStyle):

{Interior = Pattern; None; WindowText; Lime
}

What I want to do is remove all the properties that are set in the new row style from style of each cell in the row. So in this case, I want to remove "Interior = etc" from the cell as it is the only thing shared by the cell style or the row style.

I call this line of code to attempt to do this:

theRowStyle.ModifyStyle(theCellStyle, Syncfusion.Styles.StyleModifyType.Exclude);

What I would expect after that operation is that theCellStyle would look like this:

{Format = "#,##0"
Borders.Top = Solid; Black; ExtraThin
Borders.Bottom = Solid; Black; ExtraThin
VerticalAlignment = Middle
ShowButtons = ShowCurrentCell
}

However, it actually ends up like this:

{Borders.Top = Solid; Black; ExtraThin
Borders.Bottom = Solid; Black; ExtraThin
}

Is this a bug? Or am I doing something wrong?
