I am using the WPF datagrid, I have added the columns DataGridComboBoxColumn, DataGridTemplateColumn programatically.

I want every row (every comboBox) of the the column with the different datasource may be first row’s dropdown will have 5 items and second row’s dropdown will have 3 items.

C#

DataGridComboBoxColumn colcombo = new DataGridComboBoxColumn();
colcombo.Header = "FirstName";
dataGrid1.Columns.Add(colcombo);
         //===================================================================
DataGridTemplateColumn cbColcmbBox = new DataGridTemplateColumn();           
cbColcmbBox.Header = "LastNamecombo";
FrameworkElementFactory factorycombo = new 	FrameworkElementFactory(typeof(ComboBox));
DataTemplate cellTemplatecomb = new DataTemplate();
cellTemplatecomb.VisualTree = factorycombo;
cbColcmbBox.CellTemplate = cellTemplatecomb;            
dataGrid1.Columns.Add(cbColcmbBox);

Is this the correct way to add the DataGridTemplateColumn , if I want to access this programatically ?

Always use PRE tags to format the code part. It makes the question readable

If you want to add every row of your datagrid with multiple datasource dropdown then above logic want work, then you have to write code on rowload event.

Take a tempate column with blank stackpannel and in rowaoad event take new dropdown with different databasource and add it in relavnt stackpannel.

C++

stkpnl.child.add(objdropdown);

Thanks,
