[Solved] Unable to capture Expanding or collapsing event on Group by

[Deepak Agarwal]

Hi

I am making an application where I used the Telerik grid. I filled the grid with thousand of records. I made a timer in application which execute in every 45 second and on every execution it refill the Grid with those records.

Now if I applied group by on Grid for one column (you can see in attachment “1.jpeg”) then by default all group come in expand mode (I set at design time) and now I collapsed all group (you can see in attachment “2.jpeg”)

 So when I do Group by then through GroupDescriptor class I am able to store the Group by Column so when my Grid Refill in 45 second I applied the Groupby column as it was earlier (before Refill) so if i do not have to apply the Group by again.

But I am unable to capture the collapsing or expanding event or property if i changed property collapse from expand on any group. so if Grid refill then every group comes in Expand mode as Picture 1.jpeg shows.

Please Help Me.

Hello Deepak Agarwal,

RadGridView does not support such  functionality to capture event like IsExpandedChanged  in Grouping scenario.

Hello Deepak Agarwal,

We are still working on the implementation of that functionality. However, that issue is logged into our Public Issue Tracking System and you can vote for it thus affecting its priority.

That issue (3378) is marked as resolved in PITS. Does that mean that the group expanding/collapsing events are being added in Q3 2010 SP1?

Hi Brian Lam,

The events are available in our Latest Internal Builds and they will be also a part of the Q3 2010 SP1 release too. The two events are as follows:

private void gridView_GroupRowIsExpandedChanging(object sender, GroupRowCancelEventArgs e)
{
}
private void gridView_GroupRowIsExpandedChanged(object sender, GroupRowEventArgs e)
{
}
