Stop auto loading of TUniDBImage when underlying BLOB field changes.

[BantuKumar]

Hi uniGUI team,

 

Can we stop auto loading of image TUniDBImage when we move to next record of associated dataset or underlying BLOB field changes..

Is there any property that can control this behavior of this component. If not then is there any workaround for the same?

 

I have graphics with large data that take lot of time to load and auto loading of graphic is leading to performance delay.

 

Thanks in advance.

Hi,

 

If we avoid this, how user will be able to see the images?

Good question. 

There are two aspects of this...

1. How user will see if he/she wants
2. How a programmer will do the image visible

A user can double click on the control or press enter key to get the image where as a programmer can say loadImage (or any relevant method to load image on the control) to make graphic visible.

 

 

Thanks & Regards,

One solution is to put two sizes of image in table. One thumbnail and one real size. You will show the thumbnail in the grid.

Other solution is to remove image column from the grid and show the image in a new window when user double clicks the row.
