Question

Getting error while inserting values into database (SQL Server 2008)

Implicit conversion from data type varchar to varbinary is not allowed. Use the CONVERT function to run this query.

Code:

da.InsertCommand = new SqlCommand("insert into tblProductMaster ([Name],[Type],[Height],[Width],[Length],[Price]) values( @Name , @Type , @Height , @Width , @Length , @Price )", con);

da.InsertCommand.Parameters.Add("@Name", SqlDbType.VarChar).Value = txtName.Text;
da.InsertCommand.Parameters.Add("@Type", SqlDbType.VarChar, 10).Value = Convert.ToString(ddlType.SelectedItem);
da.InsertCommand.Parameters.Add("@Height", SqlDbType.Float).Value = float.Parse(txtHeight.Text);
da.InsertCommand.Parameters.Add("@Width", SqlDbType.Float).Value = float.Parse(txtWidth.Text);
da.InsertCommand.Parameters.Add("@Length", SqlDbType.Float).Value = float.Parse(txtLength.Text);
da.InsertCommand.Parameters.Add("@Price", SqlDbType.SmallMoney).Value = int.Parse(txtPrice.Text);

da.InsertCommand.ExecuteNonQuery();

Answer 1

I would imagine that the Name or Type columns in your table are of type varbinary and you are trying to set them to be a varchar
