Changed behaviour: now doesn't select the old row (Q2 2010 SP2)

[Francesco Pezzato]

Hello,

I've developed an application using winForm Q1 2010 (on VS2008, .Net3.5);
 Today I've installed the version Q2 2010 SP2, but I've found some differences.

#Question1:
In version 2010 Q1  the gridview was very smart:after re-assigning the datasource, the grid remembers the "old" selected
row and automatically re-select the row.
In the new version(2010 Q2 SP2) this behaviour seems different, the grid selects the first row.

Do you have changed something about that? How can I re-activate the behaviuor?

#Question2:
Following this page (http://goo.gl/PM8T) I've "upgraded"  my app (1 solution, 5 projects, about 20 grids),
but now some grids (not all of them!!) have lost the settings (e.g. the showRowHeaderColumn property)and the skin: did you have ever seen something like that?
I really can't find any differences in the grids (all of them have the same properties).

I've readed this forum, founding nothing about: do you have any advice for me?

 

Thanks in advance
Francesco

Hello Francesco,

1. Sorry, there is no way of using the old behavior, i had the same problem when i first switched to Q2 but in time you will learn to appreciate the performance boost the new and improved grid has to offer.

2. This usually does not happen, but the problem with this is with the visual studio designer's serialization mechanism, and sadly you have no other choice than to fix all of them by hand (or if you have an older version just copy the designer files from there, it should work). That's why I usually prefer to have make as much customizations i can without the help of the designer, safer and more maintainable.

Hope this helps, if you have any other questions or comments, please let me know,

Best Regards,

Hello Emanuel,

thank you for your answer!

Ffor the #Question1, I have to revert the pojects to the "2010 Q1" version of the library, because now I have no time to check and modify the whole application...so sad by now:(

Thanks,

Francesco

I honestly hope you change your mind and update to the latest version, i believe you will see very soon some performance increases and a lot of issues fixed.

And if you need any help, I am more than happy to help you during the update process.

Hi, 

I know this is not the answer you were looking for, but I just wanted to second what Emanuel was saying. It was only slightly painful to update to the latest version (changing over properties and so on) but the effort is well worth it.

Hi Francesco,

You can use the following code in order to preserve the current row when rebinding:

int scrollbarValue = this.radGridView1.TableElement.VScrollBar.Value;
int index = this.radGridView1.Rows.IndexOf(this.radGridView1.CurrentRow);
this.radGridView1.DataSource = table;
if (index >= 0 && index < this.radGridView1.Rows.Count)
{
    this.radGridView1.Rows[index].IsCurrent = true;
    if (scrollbarValue < this.radGridView1.TableElement.VScrollBar.Maximum - this.radGridView1.TableElement.VScrollBar.LargeChange + 1)
    {
        this.radGridView1.TableElement.VScrollBar.Value = scrollbarValue;
    }
}

I hope this helps.

Sincerely yours,
