Combo Box in Hierarchy GridView

[Sakthi]

Hi,

I have implemented Hierarchy gridview. while clicking "+" sysmbol in the gridview row it will display childviewTemplate with related to the parent row. Currently I have two rows in my child table. So it is displaying those rows in the childviewTemplate. In the Last row of child Gridview  i need to display the combox for the first column. 
I  am trying to bind the data at runtime using C# in winForms. So please any help me on this to display combo box in the Hierarchy gridview.

Regards,
Sakthi

Hi Sakthi,

Thank you for writing.

In regards to your question concerning adding a RadComboBox into the first column and last row of a child template, please consider the following code snippet:

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{   //ensure we are in a child
    if (e.CellElement.RowInfo.Parent != null)
    {   //ensure that we are modifing children only for row with ID (which is a column in the row) = 1
        if (int.Parse(((GridViewDataRowInfo)e.CellElement.RowInfo.Parent).Cells["ID"].Value.ToString()) == 1)
        {   //find a certain column in the child by uniqueName
            if (e.CellElement.ColumnInfo.UniqueName == "ID")
            {
                GridViewInfo gridInfo = e.CellElement.RowInfo.ViewInfo;
                int rowsCount = gridInfo.Rows.Count;
                //If we are on the last row
                if (e.CellElement.RowIndex == rowsCount - 1)
                {
                    if (e.CellElement.Children.Count == 0)
                    {
                        RadComboBoxElement combo = new RadComboBoxElement();
                        e.CellElement.Children.Add(combo);
                    }
                }
            }
        }
    }
}
