I have a stored procedure that has 2 varchar and 4 int parameters. I want to read content of textbox and filter SqlDataSource but when I set all of the parameter type to string and I don't use varchar parameter all the things is right but when I add string parameter do not work;
   <asp:Parameter Name="ProviderBranchID"  DefaultValue="null" Type="Int32"/>
   <asp:Parameter Name="RequestBranchID"   DefaultValue="null"  Type="Int32"/>
   <asp:Parameter Name="CustomerNo"   DefaultValue="null" Type="Int32" />
   <asp:Parameter Name="BoxesTypeCode"  DefaultValue="null" Type="Int32" />
   <asp:Parameter Name="BoxesName"   DefaultValue="null" Type="String" />

and code behind in Selecting event is...

temp1 = TextBox1.Text;
temp2 = TextBox2.Text;
temp3 = TextBox5.Text;
temp4 = TextBox6.Text;
temp5 = TextBox4.Text;
temp6 = TextBoxName.Text;

e.Command.Parameters["@RequestBranchID"].Value = Convert.ToInt32(temp1);
e.Command.Parameters["@ProviderBranchID"].Value = Convert.ToInt32(temp2);
e.Command.Parameters["@CustomerNo"].Value = Convert.ToInt32(temp4);
e.Command.Parameters["@BoxesTypeCode"].Value = Convert.ToInt32(temp5);
e.Command.Parameters["@BoxesName"].Value = temp6;

It consider String as Unicode character. That is the problem. Change to NVarchar in Sql it should go fine.
