GridGroupingControl : change the selected record/row in drag over event

[clement]

when I drag an item over the grid, can it change the selected record(or current element) as well? Because I need to get the value of the record when I do ''drag leave event''.

thank you

Hi Clement, Sorry for the delay in responding. I have updated your previous forum thread. http://www.syncfusion.com/Support/forums/message.aspx?MessageID=42942 Regards, Calvin.

Thank you Calvin!

1) in your sample (HighLight.zip), When I drag over the grid, one row''s color will change to red color based on the X and Y axis. My question is when I release the mouse''s button(or DragLeave), how to move the current selected row to the row which I release the button(make it be the focused row)?

2) After I run DoDragDrop(gridGroupingControl1.DoDragDrop("test", DragDropEffects.Move | DragDropEffects.Copy)) , I cannot click the ''PlusMinus icon''. Why?

Thanks.

Hi Clement, Attached is a rough try sample to move the record by DragDrop. While doing drag drop over the nested table you have to also take care of the parent id value. And I was not able to reproduce the send issue. It works fine even after calling the DoDragDrop. Can you see the issue in the attached sample? Regards, Calvin.

Sorry, Calvin

I explain what problem I face again :

There is a arrow in the current selected record. My question is how can I change the selected record during ''DragLeave or DragOver''?

Thanks, Calvin

Hi Clement,

Sorry for misunderstanding your question. The current record can be retrieved using the below snippet code and the current record values can be changed using the record.SetValue() method. The DragLeave event will be triggered when you drag and leave the grid control. The current record values can be set just after calling the DoDragDrop to change the record values after doing drag drop from the grid to some other control, since you know when DoDragDrop mode ends that is when the call to DoDragDrop returns. The below snipped code can aslo be used to cahnge the current record values in the DragOver event handler.

Element inEl = this.gridGroupingControl1.Table.GetInnerMostCurrentElement();
if (inEl is GridRecord)
{
GridRecord rec = inEl as GridRecord;
System.Diagnostics.Debug.WriteLine(rec);
rec.SetValue("colName", value);
}

Let us know if you are trying for something different. Hope this time I got your requirement, but not sure.

Regards,
Calvin.

Thanks, but that is not what I want. Let''s hold it first. I did attach the program (Based on your sample[42942]) to you. Can you help me to check the problem : 1) after I did add the ''Drag Drop Event'', I cannot expend the child table any more, Why? Thank you calvin

Hi Clement, Please refer to the modified sample. In the MouseDown event handler, only if the clicked cell is a RowHeaderCell then the DragDrop operation should be done. I have uncommented the conduction checking that you have commented. And hope this will answer also for the first question. Regards, Calvin.
