Collapse all records

[Plotnikova]

Hello,

We use GridGroupingControl.
In toolstrip we have a possibility to expand and collapse all records. [grid.Table.ExpandAllRecords(); and grid.Table.CollapseAllRecords();]

If the user clicked on the Collapse All and tries to expand one node, no records will be shown in child table just header.

How can I fix this problem?

Thanks
Best Regards

Hi Plotnikova,

The collapseall code is collapsing the groups, and if you want them expanded again as you click the parent record's expand button, then you will have to explicitly expand them at that point. This was done by adding a RecordExpanded event handler and doing it there.

See the code:

bool ignoreExpand;
void gridGroupingControl1_RecordExpanded(object sender, RecordEventArgs e)
{
if (ignoreExpand)
return;
ignoreExpand = true;
if (e.Record.NestedTables.Count > 0)
{
GridNestedTable nt = e.Record.NestedTables[0] as GridNestedTable;
nt.IsExpanded = true;
}
ignoreExpand = false;

}

Please let me know if this helps.

Regards,
Jisha

Hi Jisha,

thank you so much. It helps.

What can I do if by expanding all records I don't want to show the nested records, if the count of nested records is 0.

Hi,

the problem is, when I override a Factory, all others grid in project where sorce has 0 items will not be displayed.

[Plotnikova]

I have added the extra condition [this.Engine.TableDescriptor.Relations.Count>0 ] in this new Factory for functions of overriden class GridChildTable.
So it means if the other grid, that does not have children, will be displayed.

I hope that this solution will work reliable.
