How can i place a sub-columns inside a datatable column???

[Daniel Santos de Carvalho]

I wanted to place a column (days) in my datatable with many sub-columns inside it. Each of this sub-columns will have a different day with different data inside. Any idea how to place a column inside other???

Hi Daniel,

Sorry for the delay in response.

You need to use the custom cell type for storing the different value in a single cell. It requires a model class and a renderer
class. The model class handles the serialization requirements for the control and creates the renderer class. The renderer
class handles the UI requirements of the cell. Then to use the custom cell type in a grid, you need to register this celltype
with the grid. Below is the code snippets:

this.gridGroupingControl1.TableModel.CellModels.Add("TwoTextBoxCell", new TwoTextBoxCellModel(this.gridGroupingControl1.TableModel));
this.gridGroupingControl1.TableDescriptor.Columns["Customers"].Appearance.AnyRecordFieldCell.CellType = "TwoTextBoxCell";

Please refer this sample that implements the split column cell type.

It implements the GridGenericControlCellModel and GridGenericControlCellRenderer for creating a custom cell type in a grid.

Kindly let us know if you need any further assistance.

Actually, i'm looking for something that allow the "colspan" effect of the html in the header.

There is a way to put a text that take the header space of many columns??

Hi Daniel,

Thank you for your update.

You can achieve the column spanning of header by handling the QueryCoveredRange event. Here is the code snippet that shows merging a range of columns using QueryCoveredRange event.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
int col1 = 3,col2 = 4;
private void gridGroupingControl1_QueryCoveredRange(object sender, GridTableQueryCoveredRangeEventArgs e)
{
GridTable thisTable = this.gridGroupingControl1.Table;
if (e.RowIndex < thisTable.DisplayElements.Count)
{
Element el = thisTable.DisplayElements[e.RowIndex];		
if(el.Kind == DisplayElementKind.ColumnHeader)//.Record)
{
if(e.ColIndex >= col1  && e.ColIndex <= col2)
{						
e.Range = GridRangeInfo.Cells(e.RowIndex, col1, e.RowIndex, col2);		
e.Handled = true;						
}
}					
}	
}
