Hi Ravi,

Please try this code to assign the datsource of the combobox cell in a grid during runtime.

//For comboboxcell type column 2
this.gridControl1[1,2].DataSource = GetTable(cc.Renderer.ControlText);
this.gridControl1[1,2].DisplayMember = "Name";
this.gridControl1[1,2].ValueMember = "Value";

Here is a sample for implementing it.

Hi

We are having our own datasoruce ( its an array of objects). In QueryCellInfo event we are setting the values for each cell during runtime by assigning the values from our datasoruce..

if (e.RowIndex > 0)
{
e.Style.CellValue = m_document[e.RowIndex - 1, e.ColIndex];
e.Handled = true;
}

where m_document is collection of objects. Now here in one of the col I want to have combobox.
I dont knwo how to bind the combo with another datasource ( array of country objects) ..

Pls reply me AEAP.

Thaks
Ravi

Hi Ravi,

Could you try this code to configure the combobox celltype.Here is a sample.

if(e.ColIndex == 2 && e.RowIndex > 0)
{
// For more than on element in a arraylist e.Style.DisplayMember/ValueMember is necessary for showing the element.
e.Style.DataSource = GetList(m_document[e.RowIndex - 1, e.ColIndex].ToString());
e.Style.CellType = "ComboBox";
}

Here is a sample.
