Customize text in GroupCaptionCell

[James Blibo]

I have a ggc that has 1 level of grouping.
Assuming my the name of my group column name is 'ModelName', the ggc always display the text in the GroupCaptionCell as {GroupName}: {GroupNameText} - {} items

for example, if my current model group is 'Cars', the GroupCaptionCEll would show

ModelName: Cars - 23 items.

In my actual datasource, I also have the ModelID along with the ModelName. How do I add the ModelID as part of the ModelName in the GroupCaptionCell. The ModelID and ModelName will always have a 1 to 1 match.

Hi James,

You can handle the QueryCellStyleInfo event to set the Style property of the GroupCaptionCell. See the below code snippet for more details.

private void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
if( e.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionCell
&& e.TableCellIdentity.GroupedColumn != null &&
e.TableCellIdentity.GroupedColumn.Name == "Cars" )
{
e.Style.Text = "YourDisplayText Here";
}
}

I understand how to do that... I guess my issue is-> How do I get access to the records collection for this this GroupCaptionCell is the parent of?

Hi James,

You can get the caption row from the displayelement and access the related records using the GridCaptionRow. Here is a code snippet to show this.

private void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
if( e.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionCell
&& e.TableCellIdentity.GroupedColumn != null &&
e.TableCellIdentity.GroupedColumn.Name == "Cars" )
{
// get the CaptionRow from the DisplayElement.
GridCaptionRow gr = e.TableCellIdentity.DisplayElement as GridCaptionRow;

//Accessing the related records in a Group...
foreach(Record rec in gr.ParentGroup.Records)
{ Console.WriteLine("Records:" + rec); }
}
}
