i think same situation occurs in my app. I fixed it by adding a timer, that can refresh grid max once per each 500 msec. When grid needs to be refreshed, i am triggering a flag and when timer fires, it checks for that flag and updates a grid if required. But still, sometimes iam getting that av (maybe 500msec is not enough for full draw).

Waiting for ur solution

Hello Saurman,

TTimer is also some kind of TThread, but I definitelly need to change something in my Grid.

There is no problems where cell's data are changed but as you may see problems occur when rows are deleted/added.

boki, is it possible in slide mode, to draw text cell over image cell with transparent background?

[Boki (Berg)]

Hello Saurman,

I am not sure that I understand

Can you please send me one small screenshot or sketch about what you try to archive?

Please don't forget that you may overlap cells in slide mode.

well, here is a screen:


I want another text cell, to be drawn over the left big image (its img cell), but the drawn text should have a transparent background (i want kind of draw text over image)

[Boki (Berg)]

Hello Saurman,

Maybe settind DrawingOptions property of text Column to doCustomOnly. Then with using CustomDrawing (Tutorial), and TextOut command simply draw text.

I think that this should go. If you having troubles, I may made one sample.

Best regards

hmm, maybe its better to have column Transparent property in slide mode?

[Boki (Berg)]

Hello Saurman,

I have this property in plan, but until it is added I suggest approach from previous post.

Best regards

hey Boki, i have a small suggestion to slide mode. Would be good if slide could have two display modes. 1st mode - is just normal slide, like it is now. 2nd mode - completely another slide which will have a separate design window. This second slide type will override 1st style for selected grid row.

Here is a small example. Lets say u have grid in slide mode. Each slide shows some simple info from grid row. But when slide becomes selected, it will be displayed as a completely another slide which i will design in slide editor. So if i selecte slide, it might get new height and will show me more columns - kind of more detailed information for selected row.

so basically what i suggest is:
1) add flag to enable that mode
2) add slide 2nd style editor. 1st style editor u already have, so it shouldnt be a problem
3) selected slide will be displayed using second style, non-selected - using 1st style. Kind of "customized selected slide view". This will be usefull, when while not selected, row can show only basic info, but when u do select it - more detailed.

What to u think Boki?

Hello Saurman,

I am sorry for delay, I was miss this post after I have open forum next time;

Idea is fine, but I will need to deep think about it and not sure that I will implement it. I will notify you if I decide to do with it, but again I can't promisse anything.

Thank you for this idea, waiting for other ideas too

Best regards

Hey Boki, one more thing i've just found. I am trying to print money sums in separate column i cant use number column because its based on TMask. I want to get result, similar to this:

CODE

ShowMessage(Format('Money = %m', [12345.678]));  //Money    = $12,345.68

Thats why iam using Text Column and format each value manually. But after that i cant use CalculateFooter, it doesnt recognize that value as float. Any solution?

[Boki (Berg)]

Hello Saurman,

I suggest using NumberColumn and set $ in TextBefore property of Column. Also, set FormatMask to desired mask (example: #,##0.00).

Then you will be able to use CalculateFooter.

Best regards

[Saurman]

well, it works for cells, but footer's FormatMask is messed up. It doesnt work in same way as in cells. I want the footer to print data in same format as cells

[Boki (Berg)]

Hello Saurman,

I think that you need to set Footer.FormatMaskKind to mkFloat.

Best regards

[Saurman]

it works, thx Boki

Btw, is it possible to have such sort of header in grid?


TMS already have it i think, i saw it somewhere cant remember where

[Boki (Berg)]

Hello Saurman,

This feature is planed, but please note that it will take a some big amount of time to implement all this.

Best regards

Hey Boki, here is my problem.

I have a grid with over 2k rows. I am doing full update and this moves a position of the scrollbar and selecting. How can i restore last view of the grid (a range of the viewable rows before grid update) after update?
