when I used databound for get the value from database, how can I hide or (make some items invisable) from this combo.
when I tried to delete some items the following error occur
Items collection cannot be modified when the DataSource property is set.
best regards

first make a DataTable from current ComboBox DataSource:

DataTable dt =(DataTable) comboBox1.DataSource;

then find target item in DT and remove it from DT.
then set again DT for comboBox datasourse:

  DataTable dt = (DataTable)comboBox1.DataSource;
DataRow dr = dt.Rows.Find("TargetKey");
comboBox1.DataSource = dt;
Hello somur-ruteeb,

Try out this..

Instead of binding the the collection to the combobox datasource you've added items to combobox.Itemscollection for each row. This way we can have different values for each row in the combobox.
