Comobox Combinatorics - Selected Value Is ALL In The Combo X, I Cannot Get The Values?

i have a form with 3 combo boxes. The value of the combo boxes generates a sql query with 3 parameters. The sql generates a RDLC report.

For example:

Combox1 with values(v1,v2,v3,ALL)

Combox2 with values(v1,v2,ALL)

Combox3 with values(v1,v2,v3,4,ALL)

Me.ExampleTableAdapter.QueryWithParams(Me.ExampleDataSet.Table, Combobox1.SelectedIndex, Combobox2.SelectedIndex,Combobox1.SelectedIndex)

QueryWithParams:SELECT * FROM Table WHERE Column1=@c1 AND Column2=@c2 AND Column3=@c3 Ok the problem is when the selected value is ALL in the combo X, i cannot get the values because i must change the query and kick out the parameter.For example:If the combo1,combo2,combo3 have the values ALL. I don't need parameters.SELECT * FROM Table IF the combo1 is ALL.SELECT * FROM Table WHERE Column2=@c2 AND Column3=@c3 If combo1 and combo3 are ALL SELECT* FROM Table WHERE Column2=@c2 Then in code I look which is the selected value of the combo and upon it i do the query.Is there a way that i do this thing without generating all 8 types of queries?PS. I cannot use stored procedures because i'm using SQL Server Compact
